How to delete a specific route from route collection in nopCommerce 4.3

Hi,
In nop4.2, I can easily find any route what I can remove. But in nop4.3 I face some dificulties. Please see below if anyone could advise me regarding this issue.

In nop4.2

public void RegisterRoutes(IRouteBuilder routeBuilder)
{
    foreach (Route item in routeBuilder.Routes)
    {
        if (item.Name == "ProductSearch")
        {
            routeBuilder.Routes.Remove(item);
            routeBuilder.MapLocalizedRoute("ProductSearch", "search/",
                new { controller = "XyzSearch", action = "Search" });
            break;
        }
    }
}

What I will try to do in nop 4.3 ?
