UEFI password reset on Surface Pro 3

Good evening. I bought a Surface Pro off eBay. Unfortunately, it arrived with a password on the UEFI. I found an article that said I could reset the password by downloading the restore image from Microsoft. I tried that and it’s still locked. Does anyone have any idea what else I can do?

Is there a way to take apart laptop and jumumper pin reset bios? Or perhaps reflash bios with connection directly to board? Or, perhaps if all else fails a person could give the board a virus with a linux vm connected otg. I’ve seen it done on desktop (asus hero viii).
