Do things the right way and get it repaired at a quality shop (yes they will most likely report it to CarFax). With that being said, damage will show as minor and as long as it was a quality job you won’t take as much of a hit in value. Believe me, people who will appraise your car in the future can tell if it’s been in an accident, regardless of the records and especially if you repair it at a shitty shop
