I have configured my server to serve only https creating a self-signed certificate. I have noticed that, a HTTPS connection can be set up with the server configured to use a certificate, and when additional security is required, the server can ask the client to provide a client certificate, validate it and set up connection.

This reverses the roles of both machines, and also the security guarantees: the machine S will have a good idea of the identity of the connected client C, but the client C will not be sure of what server S it is talking to (an attacker could have intercepted and redirected the communication). so you can use mutual TLS for authentication & encryption. Besides, this would never work. MySQL Server works in client/server or embedded systems. Can HTTPS server configured without a server certificate?
