Enable/disable an effect via a binding - xamarin.forms

Question

In Xamarin Forms, an effect can be added in XAML, like this:
<Label ... >
<View.Effects>
<effects:MyGlowEffect Radius="10" Color="White"/>
</View.Effects>
</Label>
GOAL:
I want this effect to only be active when a boolean in my ViewModel is true. E.g. the equivalent of (fake code - no such property "IsEnabled"):
<effects:MyGlowEffect Radius="10" Color="White" IsEnabled="{Binding EnableEffect}"/>
How can I accomplish this?
I thought of using a Trigger, but I don't understand how a trigger could attach/detact an Effect. Nor how to have the Effect written in XAML, if it is sometimes attached and sometimes not.
I'm not looking for an answer that involves a custom renderer, or re-writing the effect as something else (a behavior?) - unless that is an easy rewrite. Because the effect already has been written, and this dynamic attachment is only desired in one place.
MY FALLBACK DESIGN:
If there is no simple solution, I'll make two versions of the View that needs the effect: one with it and one without it. Have the binding control which of those is visible - I already have the InverseBooleanConverter that is involved in that solution. Which looks like this:
<Label ... IsVisible="{Binding EnableEffect}">
<View.Effects>
<effects:MyGlowEffect Radius="10" Color="White"/>
</View.Effects>
</Label>
<Label ... IsVisible="{Binding EnableEffect, Converter={StaticResource InverseBooleanConverter}}"/>
UPDATE:
Since this is my own custom effect, this should be solvable by adding a custom parameter, and binding that to the boolean in ViewModel as in Docs: Passing Effect Parameters as Attached Properties. (AFAIK, must use "attached" property, in order to use a Binding - effect properties don't appear to respond to dynamic changes.)
However, if there is some "generic" way to do this, for example to enable/disable an effect that I don't have source to, I would prefer that as a solution.

Your were totally right about triggers, you can modify the existing like in my sample, or just add a new one like i guess you wanted:
<Label ...>
<View.Effects>
<effects:MyGlowEffect Radius="10" Color="White" />
</View.Effects>
<Label.Triggers>
<DataTrigger Binding="{Binding EnableEffect TargetType="Label" Value="true">
<Setter Property="effects:MyGlowEffect.Radius" Value="11" />
<Setter Property="effects:MyGlowEffect.Color" Value="Red" />
</DataTrigger>
</Label.Triggers>
</Label>
