How to I close port 3389 on a remote computer and open another port on remote computer, for RDP connection?

I want to close port 3389 on a remotely accessed computer and open a different port to remotely access the computer.

eg.

Currently: My computer > RDP > port:3389 (open)/remote computer

What I want to do: My computer > RDP > port:3389 (closed), port: XXXX (open)/remote computer.

Any ideas how I can achieve that?
