How to override a function in parent WordPress theme - wordpress

Question

I am building a child theme using Flaxseed as a parent. This theme includes several 'content styles' which can be selected using Theme > Customizer. Each of these styles has a function in the parent functions.php file that renders the CSS and wordpress content into one. I want to edit some of the Loop functions that are in here, specifically updating the_excerpt to the_content, but I want to do so in a way that works with my child theme.
Since this code is in the parent functions.php, and since the theme customizer calls it specifically by name, I cannot simply add a new function, and I cannot override it using the same function name.
My best guess is that I need to somehow remove this function from the parent functions.php before loading a new function of the same name in my child function.php, but I cannot seem to figure out how.
Below is the code from the template file where the function is loaded into the template:
<?php for ($i = 1; $i < 8; $i++)
if (get_theme_mod('flaxseedpro_fa_'.$i) != 'none') {
flaxseedpro_display_featured_area(
get_theme_mod('flaxseedpro_fa_'.$i),
get_theme_mod('flaxseedpro_fa_title'.$i),
get_theme_mod('flaxseedpro_fa_cat'.$i)
);
}
?>
Here, the $i variable is the value that is set in the Theme > Customizer screen. This file and code could be modified easily as a part of the child theme.
Below are two code snips from the parent functions.php which select the appropriate featured area code:
function flaxseedpro_display_featured_area($style, $fa_title, $cat) {
if (is_home()) :
switch ($style) {
case 'carousel':
flaxseedpro_carousel($fa_title, $cat);
break;
case 'style1':
flaxseedpro_featured_style1($fa_title, $cat);
break;
case 'style2':
flaxseedpro_featured_style2($fa_title, $cat);
break;
case 'style3':
flaxseedpro_featured_style3($fa_title, $cat);
break;
case 'style4':
flaxseedpro_featured_style4($fa_title, $cat);
break;
default:
break;
}
endif;
}
which leads to several functions such as this:
function flaxseedpro_featured_style2($fa_title, $cat) {
?>
<div class="featured-style1 featured-style2">
<?php if ('' !== $fa_title) : ?>
<h2 class="featured-section-title container">
<?php echo esc_html($fa_title); ?>
</h2>
<?php endif; ?>
<div class="featured-posts-inner container">
<?php
$args = array(
'posts_per_page' => 5,
'cat' => $cat,
);
$fa_posts = new WP_Query($args);
if ($fa_posts->have_posts()) :
$counter = 0;
while ($fa_posts->have_posts()) :
$fa_posts->the_post();
$counter++;
if (1 === $counter) {
?>
<div class="feat-col1 md-6 sm-6">
<div class="md-12 pr-0 pl-0">
<article id="post-<?php the_ID(); ?>" <?php post_class('featured-post-item'); ?>>
<div class="item-container mb-3">
<?php if (has_post_thumbnail()) : ?>
<?php the_post_thumbnail('medium-large', array('class' => 'featured-post-thumbnail-primary')); ?>
<?php else : ?>
<img src="<?php echo esc_url(get_template_directory_uri() . '/assets/images/placeholder.png'); ?>">
<?php endif; ?>
</div>
<div class="post-title-parent">
<a class="post-title title-font" href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<div class="post-author">
<?php esc_html_e('By', 'flaxseed-pro'); ?> <?php the_author(); ?> <i class="fa fa-clock-o"></i> <?php the_time('F j, Y'); ?>
</div>
<div class="entry-excerpt body-font mb-3"><?php the_excerpt(); ?></div>
</div>
<?php _e('Read More','flaxseed-pro') ?>
</article>
</div>
</div>
<?php
} else {
?>
<div class="feat-col2 md-6 sm-6">
<article id="post-<?php the_ID(); ?>" <?php post_class('featured-post-item'); ?>>
<div class="md-4 xs-4">
<div class="item-container">
<?php if (has_post_thumbnail()) : ?>
<?php the_post_thumbnail('medium', array('class' => 'featured-post-thumbnail-secondary')); ?>
<?php else : ?>
<img src="<?php echo esc_url(get_template_directory_uri() . '/assets/images/placeholder.png'); ?>">
<?php endif; ?>
</div>
</div>
<div class="md-8 xs-8">
<div class="post-title-parent">
<a class="post-title title-font" href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<br><small><?php esc_html_e('By', 'flaxseed-pro'); ?> <?php the_author(); ?> <i class="fa fa-clock-o"></i> <?php the_time('F j, Y'); ?></small>
</div>
</div>
</article>
</div>
<?php
}
endwhile;
endif;
wp_reset_postdata();
?>
</div>
</div>
<?php
}
This is the the code I've been trying to override but unable to find a solution as a part of the child theme. All of the answers I've found seem to require a hook, which I cannot discern from this code.

Answer 1

This is solved.
I changed the function name that is called in my template file (flaxseedpro_display_featured_area >> flaxseedpro_display_featured_area2), then redefined the switch function to replace 'style3' with a new 'style5'. Then added the new 'style5' function with updated CSS code.
