Nozzle scrape line in textured PEI plate - fixable?

In the very start of my journey in printing, the nozzle offset was set way, way too low and dug into the textured PEI plate that comes with the k2 plus. Needless to say, it leaves its impression on all prints now (it’s from the front to the back, think end of print travel back to the nozzle cleaner). Is there a way to fix this or is the plate hosed?

Had a few of those early in my journey, yeah, it’s pretty much always going to have that mark now. Plates are generally pretty inexpensive to replace though. I keep 4-5 on the go usually, and I still use my damaged ones for draft copies, untested filaments, or anything that might not need to print in damaged areas.

I found this and I’m going to give it a shot: https://forum.seemecnc.com/viewtopic.php?t=10531
