Hi.
A server configuration may help, but unluckily it is currently not working correctly. You can read about it here and maybe subscribe the Trouble Report to be notified when we’ll release the fix:

While waiting for this fix, if you’ve control over client machines you may pre-configure a connection file and lock it down by setting it as read-only, so credentials will never be stored. Of course the drawback is that also settings changed by users will not be saved.
About console command, you can start a connection with the command nxplayer --session <path to NXS file>
. I’m not sure it is what you need, but you may give a try and tell me if it fits your needs.
