You mean the, for example, SSH-1.5-1.2.27 which the server sends after
accepting a connection on its listening port?

It's not a telnet banner, it's a part of the ssh protocol.  You can
change some of it without breaking it, but if you can't figure out what
you can change and how to do it, you shouldn't.  Why you would want to,
I have no idea.  Security through obscurity won't help you if you're
running a vulnerable sshd.
