Something like this might work. This has not been tested. The “current_screen” hook is the earliest hook you can use in this example and I do not know if this is too late to add the filters for the custom location rules.
add_action('current_screen', 'maybe_add_filters');
function maybe_add_filters() {
if (function_exists('get_current_screen')) {
$screen = get_current_screen();
if ($screen->ID == 'acf-field-group') {
return;
}
}
// either not in admin or not editing a field group
// add filters for location rules
add_filter('acf/location/rule_types', 'acf_location_rules_types');
// etc...
}
