It is possible, but you have to unsolder the NOR flash.
I did this in the past on a board to change a sound codec.
You then have to solder a new NOR flash if you want to try to flash u-boot again on it.
To unsolder such chip, the best is to use a knife first to cut the feets, then remove them with the iron.
Use a lot of flux and copper braid.
You should train yourself to solder and unsolder SMD on old broken electronics.
