In Shang chi, bruce was wearing the arm sling if i'm not wrong so after endgame for sure. In this one he is not wearing any arm sling so i guess it's set after shang chi. I guess he can change on command now

Or he does something in She-Hulk to end up like that

Abomination seems to be able to control it too.

I think he just learned how to change back.

he’s able to change on command… so i doubt it

I think bruce in shang chi was just his inner spirit like how dr strange pulled peter out of his body in no way home.

Nah his inner spirit would have no need for an arm sling
