Hi @PDeT,
you can’t configure default modules.
But creating a custom module for custom icons is quite simple.
The only things you’d need are:
- text field(not rich-text) or a dropdown(If you’d like to limit the module to certain icons). I’ll call it “icon name”
- a bit of HTML
The default layout of the module should be:
<i class="fal fa-{{ module.icon_name }}"></i>
That’s it 
If you’re going the text-field way the user will need to put the icon name without “fa-” into the field like
heart, house…
Of course you can add a ton of options here like
- changing the “icon weight”
- changing the sizes
- and what ever you’d like to do
for the icon weight:
My personal favorite is to create a select option with the names and the associated values.
E.g:
Name / Value
Thin / fal
Regular / far
Solid / fas
Duo / fad
If you’d like to use something completly different like material icons this is the way to go
best,
Anton
