Preserve SVG Image-Link TCPDF/FPDI & Ghostscript - symfony

Question

In my application I utilize TCPDF to create a PDF that pastes an SVG onto it with the $link being a url that is being provided by the user so the SVG on the PDF is clickable like this
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, $pageLayout, true, 'UTF-8', false);
// remove default header/footer
$pdf->setPrintHeader(false);
$pdf->setPrintFooter(false);
// set margins
$pdf->SetMargins(0, 0, 0);
$pdf->SetXY(0, 0);
// set auto page breaks
$pdf->SetAutoPageBreak(TRUE, 0);
// set image scale factor
$pdf->setImageScale(1);
// add a page
$pdf->AddPage();
$fullPath = "$path".'qr-code/'."$uniqname".'.svg';
// Paste SVG onto page
$pdf->ImageSVG($file=$fullPath, $x=0, $y=0, $w='', $h='', $link=$query, $align='', $palign='', $border=0, $fitonpage=true);
/* Save as File */
$pdf->Output($path.'temp/'.$uniqname.'.pdf', 'F');
I then turn this PDF into a fully black CMYK PDF using Ghostscript
$targetFile = $path.'temp/'.$uniqname.'.pdf';
$iccFile = $this->params->get('ICC_FILE');
$process = new Process(['gs', '-o', $path.'pdf/'.$uniqname.'.pdf', '-sDEVICE=pdfwrite', '-sColorConversionStrategy=Gray', '-dProcessColorModel=/DeviceGray', '-dCompatibilityLevel=1.4', '-dOverrideICC=true', "-sDefaultCMYKProfile=$iccFile", $targetFile]);
$process->run();
if (!$process->isSuccessful()) {
throw new ProcessFailedException($process);
}
And at the end I merge this PDF with another containing a Logo using FDPI like so
// create second PDF document for pasting logo
$pdf = new \setasign\Fpdi\Tcpdf\Fpdi(PDF_PAGE_ORIENTATION, PDF_UNIT, $pageLayout, true, 'UTF-8', false);
// remove default header/footer
$pdf->setPrintHeader(false);
$pdf->setPrintFooter(false);
// set margins
$pdf->SetMargins(0, 0, 0);
// set auto page breaks
$pdf->SetAutoPageBreak(TRUE, 0);
// set image scale factor
$pdf->setImageScale(1);
// add a page
$pdf->AddPage();
/* Import fullHeight page */
$pages = $pdf->setSourceFile( $path.'pdf/'.$uniqname.'.pdf', 'F' );
$page = $pdf->ImportPage( 1 );
$pdf->useTemplate( $page, 0, 0 );
if($logoselect == 'eng')
{
$logos = $pdf->setSourceFile( $path.'img/engadin_online_CMYK.pdf', 'F' );
$logo = $pdf->ImportPage( 1 );
$pdf->useTemplate( $logo, 34.25, 33.75, null, 32.5);
}
if($logoselect == 'gam')
{
$logos = $pdf->setSourceFile( $path.'img/gammetermedia_CMYK.pdf', 'F' );
$logo = $pdf->ImportPage( 1 );
$pdf->useTemplate( $logo, 34.25, 33.75, null, 32.5);
}
// Close and output PDF document
$base = $pdf->Output('qrcode.pdf', 'E');
My problem now is that the link I created on the SVG of the first PDF is not in the last PDF anymore. Is there any way I can preserve this link so that it is still clickable in the last PDF or any other way I can achieve the same result?
As requested heres the initial pdf, the ghostscript output, and the final pdf
