Google Maps loading on every page

well there are a lot of code snippets here on board to deactivate google maps.
maybe something like this is working. (you can see that accept page 3184 the maps api isn’t loaded)

this comes to child-theme functions.php:

add_filter('avf_load_google_map_api', 'disable_google_map_api', 10, 1);
function disable_google_map_api($load_google_map_api) {
if( !is_page(3184) ) {
        $load_google_map_api = false;
        return $load_google_map_api;
}
}

But ! if you have the maps in the widget area you have to see how you can manage it.
And if you use some caching tools – i don’t know how if this will work too
On a test installation of mine it seems to work Link
