> The right way to do it involves a directed hot air gun and proper equipment so that you aren't imposing excessive thermal stresses onto the board as a whole. If you don't know how to do that, then please send it to someone who does. There are several good repair outfits out there right now who specialize in this and can help you out.
Even this method is fraught with danger, at least if one is doing it at home. I have decades of experience with soldering and repairing boards with SMT components and I am hesitant to use a heat gun on a board unless it's a last resort. A couple of years ago I had a Mac mini 2011 logic board with the infamous AMD Radeon BGA warping issue, and I attempted a heat gun repair following best practices. I got another six months out of the board before it started having video issues again, and another attempt to revive it failed. I didn't have anything but time invested in it (it was given to me as scrap when it failed the previous owner), but I'd never use a repaired board like that as a production machine because it will fail again and soon.
