GDPR / Google Fonts / Google API's deactivate

Hi,
at my and a client web page I have loaded uploaded the fonts as described.
Also I added the code in the functions php of the chield theme.
I tried both versions:
/* deactivate google fonts
add_action( ‘init’, ‘enfold_customization_switch_fonts’ );
function enfold_customization_switch_fonts() {
global $avia;
$avia->style->print_extra_output = false;
} */

//deactivate google font connection
function my_output_google_webfonts_script( $activate ){
return false;
}
add_filter( ‘avf_output_google_webfonts_script’, ‘my_output_google_webfonts_script’, 10, 1 );
Example URL:

https://google-fonts-checker.54gradsoftware.de/de-DE?url=https://bausanierung-trossbach.de/
The Google Fonts checkers still find google fonts.
This one finds also lot of more connections:
https://sicher3.de/google-fonts-checker/

How can I get the website DSGVO compliant and deactive al the not needed services the website connects?

I also installed the plugins:
Disable & Remove Google Fonts AND
Embed Google Fonts
Both are tested with enfold. But no change at the google font checkers.

Would be great to get your support. Thanks a lot in advance.
