Non drill option install...

Purchased this version off Amazon All-new Ring Video Doorbell | 1080p HD video, Advanced Motion Detection, and easy installation (2nd Gen) It has a drill in install option only.. due to way door is etc we cant put it on bricks and the pvc frame is not thick enough to mount onto. We have a 3 yo composite door. We dont want to invalidate any warrenty by drilling into this door.. Can anyone suggest a non drill method for installation that ring sell for this doorbell. At such a loss with finding something! Thanks in advanced
