Welcome to the forum.

As with any other service, everything downstream of the main disconnect/OCPD is wired without neutral/ground bonding.

Of course, a generator is a source, not a load, but, yes, the generator feeder and disconnect are usually also un-bonded.

K that’s what I did but noticed a different contractor left the neutral bond screw in when they did same set up in different building. I only left screw in at main disconnect.
