I'm sure there is a way, technically, to disable the camera. But any person or place that restricts the environment to 'no camera' status is not going to permit any device that has a physical camera simply because a disabled camera could be readily and discretely enabled once on the premises. Every place I've been at which does not allow cameras have required cell phones, tablets, notebook computers, and actual cameras be left in vehicles, checked into a locker - or better yet, not brought along at all.
