我相信你想要的过滤器是wp_get_nav_menus:

function wp_get_nav_menus( $args = array() ) {
    $defaults = array( \'hide_empty\' => false, \'orderby\' => \'name\' );
    $args = wp_parse_args( $args, $defaults );

     /**
     * Filter the navigation menu objects being returned.
     *
     * @since 3.0.0
     *
     * @see get_terms()
     *
     * @param array $menus An array of menu objects.
     * @param array $args  An array of arguments used to retrieve menu objects.
     */
    return apply_filters( \'wp_get_nav_menus\', get_terms( \'nav_menu\',  $args), $args );
}
