If you say that UDP is not supported, it means that UDP is not supported at all, including initiation, then it is definitely impossible to implement UDP. UDP over TCP only acts on the proxy forwarding part. UDP will still be used when the server initiates an actual request.

Your server needs to support sending UDP packets. You can set udp: false if you still want to utilize UDP, but then those packets will be initiated on your local machine and not be wrapped in TCP packets.

I've tried udp: false, but the connection uses DIRECT instead of PROXY

That's literally what he said.

If your server don't support UDP then it can't serve UDP.
