QR Code & MAC ID - Anti-Theft

I have noticed inside of my Ring stick up camera's battery compartment has both QR code and MAC ID for setup purposes. I am wondering what if I remove both stickers from the device and then mark the exterior of the device that it has no QR code or MAC ID, would that makes the theft to give up thought of stealing it? Second question is does Ring offers temper proof security screw instead of standard philip screws? If so, what is the part number for the replacement screw?
