Can I change the shape of my nostrils without surgery?

I recently had a rhinoplasty procedure done. I like the outcome however I did notice a difference in my nostrils - they both don't look the same. One is round and the other is slightly more narrow. It seems so minor to go through a surgery again. I'd prefer to adjust the round nostril to match the more narrow and natural looking one. My only setback is that I don't want to go through another surgery that will require the recovery as a rhinoplasty, so I was wondering if it can be done non-surgically.
