What to do with boobs if planning to bottle feed?

This may sound silly but with my first pregnancy my body produced zero milk after a traumatic birth so I had to bottle feed and didn’t have a single problem with leaking or pain. I’m now pregnant for a second time and I know I want to go straight to bottle feeding. If I end up producing milk this time round what do I do? If you just never use them does it stop by itself or are you supposed to release some milk/pressure periodically?
