How to use UNetTransport in Unity version 2020.2.11

Please tell me how to select UNetTransport in Unity 2022.2.11. I can’t select UNetTransport in NetworkManager due to version or settings.I can’t create Server with UnityTransport.I used many methods but can’t find the root of the problem, so I would like to try using UNetTransport. (I was able to select UNetTransport in other versions of the blank project, but not in version 2022.2.11)

UNetTransport is deprecated, so you won’t be able to use it. I’d recommend to read this first, there’s probably something that will help you.
