Google fonts pre-loaded: how to get rid of them?

Hi! Mailerlite forms are integrated on my site (in the footer of pages, like here: https://www.maisonae.fr/cuisine/blender-chauffant).

However, I can see that they require the preloading of an enormous amount of Google fonts, which slows down my site.

Please see this: https://prnt.sc/runednY0KDSu for a screenshot of usage resources. How can I prevent the forms from loading so many fonts?
