This is quite simple...
Modify the "Start" method of Scrcpy class:

public void Start(long timeoutMs = 5000)
{
    if (Connected)
        throw new Exception("Already connected.");
    Port = new Random().Next(20000, 30000);
    MobileServerSetup();
    listener = new TcpListener(IPAddress.Loopback, Port);
    listener.Start();
// ~~ snip ~~

where port is eigther a property or a field.
public int Port { get; private set; }

Then Update "MobileServerSetup" as follows:

private void MobileServerSetup()
{
    MobileServerCleanup();

    // Push scrcpy-server.jar
    UploadMobileServer();

    // Create port reverse rule
   adb.CreateReverseForward(device, "localabstract:scrcpy", $"tcp:{Port}", true);
}

You could also ask your OS for some free port number...
