Is there a way to control which TLS protocol version will be used on a certain svrconn channel? The question is related to this:

https://stackoverflow.com/questions/52208701/how-to-tell-what-ssl-tls-protocol-version-can-be-established-using-certain-ciphe

since the only channel attribute that I can imagine may influence that, is SSLCIPH. There are also some TLS related qmgr attributes, like SSLFIPS for example, then there are Channels and SSL stanza of qm.ini, but these don't seem to be related with my question. Then there is a possibility that there exists some environment variable that may influence it, but only on a global (qmgr) level.

This question is for qmgr side, I'm not interested in client side parameters which can control that.

The TLS protocol in use is dependent on the Cipher Spec being used. The control point on a channel is therefore the SSLCIPH attribute. You must indicate the exact and only cipher Spec to be used and therefore you are also controlling the TLS protocol it uses.
