You don’t even need a hole punch, just cut a hole in the digitizer part so that the lcd panel sits on top of the lens.
Camera -> Digitizer with Hole Punch -> LCD Panel -> Gorilla Glass
Then when you take a photo or video, simply do not light the pixels in the camera area where there is a hole in the digitizer.
