Disc brake or rim brake? Disc brakes installed on bikes w/o through axles can wear dropouts quickly.

Carbon dropouts? No, absolutely do not file.

Carbon forks do not ordinarily ever move around. Alignment remains as it was when fork was created. Unless they start to delaminate. That is not at all common but can happen. If it happens inside you can't see it.

Aligned forks ride way the heck better than unaligned forks.

English language can be vague and misleading and this is especially true on the intertubes. Still not clear if the wheel being reversed is centered. With or without clarity or certainty sounds like you need a new fork. Home mods to a carbon fork are just not a good idea. Most of the ideas above that will put the wheel on center still leave you with a misaligned fork. If you do have a rim brake bike the front brake isn't working properly if the fork is 2mm off. Major safety issue.
