Windows 10: How do we enable Kyber cipher suites via gpo for the ssl registry keys?

I've been attempting to enable Kyber ciphers via the registry key Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\CipherSuitesBut I can't find a format to follow anywhere; I know it runs off TLS1.2, and 1.3, which we have enabled. I'd like to enable it, but can't find any documentation on how to.

Cipher suite mismatch error

I have WCF service and a client accessing that service hosted on the same production machine(Windosw Server 2016 build)

) for testing purposes, but when the client pings the server, the call ends with an error:
Could not establish secure channel for SSL/TLS with authority 'ServerName: Port'.

When I checked the event logs, I found the following error

An unknown connection request was received from a remote client application, but none of the cipher suites supported by the client application are supported by the server. The TLS connection request has failed. (SChannel - 36874)

I tried enabling/disabling SSL, TLS security on the machine, but still not able to solve the issue.

Is there any registry key I need to set to add specific Cipher Suite to solve this issue?

Thanks in advance
