If you got a bead blaster or have access to one, that might be worth a shot.
Any sanding would probably make it stand out worse than it is.
I honestly don't know if a bead blaster or sand blaster would do anything or just bounce off but it might help camouflage it a bit.
Very fine stippling with a wood burner but you'd probably have to come up with a pattern or something and do both sides as again it would stick out worse than the scratch.
