    Example of 2 meta fields that you want to set as protected:

    function my_meta_is_protected_meta( $protected, $meta_key, $meta_type ) {

        switch ($meta_key) {
                case 'my_first_meta':
                        $protected = true;
                        break;
                case 'my_second_meta':
                        $protected = true;
                        break;
        }

        return $protected;
}
add_filter( 'is_protected_meta', 'my_meta_is_protected_meta', 10, 3 );
