Not that I am aware of. I appreciate your concern at removing the bumper cover but, if you have a space to work in, it's not a big deal. If you don't have a space to work in, you might ask an independent Volvo mechanic to re-aim your head lights. By the way did you check tire inflation and are your shocks/struts correct? Issues with the car's stance and measurement errors (not having/using a truly level surface to park to check the aim) can push the apparent headlight adjustment out of range.
