This is a great question, and and there is a lot of confusion going around as some people get this confused with the xDrive requirement, while others think you can only stray so far from the stock diameter/ratio before running into problems.
In general, RWD F-chassis BMWs don't care what your rolling diameter is. If you change it to something more than ≈2% different than stock (larger or smaller) you may feel more DSC intervention at first, but the car will eventually adapt and drive like normal. This is common when installing a square setup for the first time on a car that originally came with a staggered setup using a larger rear rolling diameter than the front.
The only thing that will actually change is the speedometer reading, which isn't typically a big deal since they read high from the factory anyway. I'd recommend using a GPS speedometer app on the first drive to get an idea of how far off the reading is at 30 and 60 MPH and keep those readings in mind.
