You can try to override the ACF settings for “enqueue_google_maps”=false for it to not load the script in the frontend. Also, I’ve added is_admin() check just to be sure that it only trigger the override on front-end.
function my_acf_init() {
if(is_admin()):
return;
endif;
acf_update_setting('enqueue_google_maps', false);
}
add_action('acf/init', 'my_acf_init');
