Tan, No, you can't control your sleep position but there's positional therapy. Look up; "Rematee AntiSnore Bumper". It's very comfortable and for me it stays on and keeps me on my side, even when I wear it loose and I don't even need the shoulder straps. It's very lightweight. I'm a small person so maybe it works better for me than for some. It's made in Canada, good quality but rather expensive, costs around $110. It comes in 4 different sizes.
Then there's a similar belt that is also comfortable, half the price, but more bulky and has more velcro. That one is called "Slumberbump" and its sold on Amazon.
Positional therapy was prescribed to me prior to cpap.
I don't always wear the belt since I have intermittent upper back pain that gets worse from side sleeping too long.
It's come in handy when I've had a cold or too much congestion for cpap.
Sometimes I wear it part of the night, along with cpap. Whatever works.
