New ring wired installation question

Hello, newbie here...Just got a Ring wired and was about to install it. Pulled of the cover to the chime box and noticed there are a front and rear doorbell currently wired. Both front and rear work. I just want to install the ring to the front door but want to make sure this will not cause any problems. The rear doorbell is never used. Do I just place the jumper on the front and trans connector of the chimebox? I guess the rear doorbell could be disconnected if i can find the transformer.
