GDPR: Remove Google Font References from Perth Pro Theme

How can I remove all Google Font references from Perth pro and other Themes and repace them with locally installed Google Fonts? I already downloaded the fonts and copied them to the /fonts directory.
I also added the new fonts th the custom css section, but there is still a still a reference to Google in the page code

Hello,

  1. Please check Enqueue scripts and styles section of theme functions.php file.

  2. You can also check this link regarding different ways of fonts adding:

  3. Please note that you’ll have to repeat functions.php file modification if you decide to edit the file directly.
