Nit: it's an "SMB" session. SMBD (SMB Direct) is the transport connection.

The use of SMB Direct is only applicable when an SMB3.x dialect is negotiated.
Is there any restriction in the use of the mount option to preclude also specifying
SMB1 and SMB2.x?

SMB version is specified in mount "-o vers=XXX". For example,  "mount -o vers=3.02" will try to negotiate SMB 3.02. I will make the change to return error on vers<3.
