Change settings of get_post_type_object

since WP 4.4.0, you can use this filter that allows you to change the arguments used in the original cpt registration.

Add this to your functions.php file:

add_filter( 'register_post_type_args', function( $args, $post_type ) {
    if( 'wyde_portfolio' === $post_type && is_array( $args ) )
        $args['rewrite']['with_front'] = false;

    return $args;
}, 99, 2 );

Hope it helps!
