Hello,
These configuration settings might be on an older version of the server. On server 2022, we can deploy cetificate by going to TASKS -> Edit Deployment Properties->Certificates if you have a remote desktop connection broker (RDCB).
If you don't have an RDCB, you can still deploy the certificate via group policy. Please follow these detailed instructions: Configuring Remote Desktop certificates - Microsoft Community Hub
Hope this helps!
Regards,
Karlie
