Front bumper repair/sensor recalibration

Does anybody have experience with repairing or even swapping out their front bumper? I ask because I recently damaged/scraped the passenger side of my front bumper + fender, and from what some of the body shops are telling me, it would require them to remove the bumper for repairs, possibly causing the Pre-Collision System (PCS) sensor to have to be recalibrated. One shop told me that Toyota Dealerships charge roughly $700-800 just to recalibrate that sensor. From what I understand, it's not 100% but the chance is there.

Has anyone had that issue come up after having to removing their bumper for repairs? Thanks in advance.
