I've been to Coz three times. In my experience, most of the operators will allow you (and some may prefer you) to doff your BC (and weight belt if not integrated) before you get back on the boat. This is especially true for the smaller "six-pack" boats many of the ops use there. Just tell them that's what you want to do.
As for the diving itself, I don't think you could exert yourself less then when you are drift diving. More or less, you will descend to the wall, remain neutral and hold position while watching the magnificent scenery go by. If you like to take photos like me, it's a tad harder because you have to acquire a photo target as it is "approaching" and then you really only get one pass as it "goes by."
On ascent, usually the dive guide will pop a bag and you'll do a floating safety stop in the current while the boat follows your bubbles.
Happy diving!
