Is there a way to access the TLS configuration?

Hey, is there a way I can access the TLS configuration? I am trying to make a demo of a factory and I need to enroll every device I “make” in a database and register it with a CSR. I have the CSR certificate (public key) which I got from OpenSSL. But now the server guys are telling me that I need to configure the TLS to add the certificate and private key for each device and I have no idea how to do that. Any tips or pointers to what I should do?
