Yes you can do in branch. It’s all about the app and face recognition. As foreigners don’t have access to the face recognition system (no idea why) then they limit transfers out of you account.
In person at a branch with a passport you can do what you like.
They used to offer a waiver where you could do transfers over 50k (face recognition is only for Thai nationals) but that’s now stopped. It might be replaced with another option but currently there isn’t any.
