Hi Kris,

Yes, you can do that. Please add the below custom code (How to add custom code?)

add_filter( 'woofc_disable', 'woofc_disable_for_mobile', 99, 1 );
function woofc_disable_for_mobile( $disable ) {
    if ( wp_is_mobile() ) {
        return true;
    }
    return $disable;
}

It will disable the Fly Cart for mobile devices.
