Question on drywalling interior gable wall for vaulted ceiling.

House was just framed, vaulted ceiling in living room only. Trusses transition from vaulted to a gable on top of the back partition wall. Haven’t drywalled one like this before.

What do you guys do to mitigate cracking from truss uplift? Would it not need an expansion joint or something on the transition from wall to structural gable?

Image is just an example from google but same situation.
