Question for rolling belly sleepers

My baby has been napping on her belly in her crib since 10 weeks, and loves it. She is easy to lay down, goes to sleep quickly, had an amazing routine, we were solid. BUT she has now learned to roll onto her back, and this makes her want to party every time and not sleep. Her 2 hour naps are now 20 minute naps. She hasn’t learned to roll from back to belly yet.

How do I help her through this?? Do I just keep trying to flip her? Put her in the baby carrier?

She is 17 weeks.
