Sorry, can’t add disable google maps function to this plugin, because it’s used to disable google fonts only. But you can add some code into functions.php in theme directory to disable google maps:

add_action(“wp_loaded”, ‘remove_google_maps_ob_start’);
function remove_google_maps_ob_start(){
ob_start(‘remove_google_maps_ob_end’);
}
function remove_google_maps_ob_end($html){
$html = preg_replace(‘/<script[^<>]*\/\/maps.(googleapis|google|gstatic).com\/[^<>]*><\/script>/i’, ”, $html);
return $html;
}
