Ortur LM2 Engraving Black Anodized Aluminum

Just purchased a 20W Ortur LM2, awaiting delivery, and bought LightBurn.

I have a black anodized surface pro 7 I’d love to engrave. I understand these diode lasers aren’t powerful enough to actually engrave metal, but it’s my understanding it should be able to take off the anodize and show the bare aluminum below.

Anyone have an experience with this? Any recommended settings?
