samba - Feb 2021 - Is it possible to set the protocol for a single client

I have a few clients which require minimum protocol. Is it possible to 
set the min protocol on a per client basis?
If so how?

You could try doing an include directive in the
smb.conf based on client machine (%m or %M) parameter.

I don't think so, SMB is a negotiated protocol, so if you set 'server 
minimum protocol = NT1' on one machine and then tried to connect from a 
machine that had 'client minimum protocol = SMB2', the client would try 
SMB3, then SMB2, then give up.

You could set the server to 'NT1' and then set individual clients to use
NT1, but this would mean your server would allow connection from any 
client that used SMB1 and I don't think this is a good idea.
