Changing the serial number in BIOS [Lenovo]

Hello all,

It’s been a while but I’ve still been lurking here and there. Today I come with a crazy prospect. Changing the serial number of a Lenovo Tiny M910q. Is that possible without any manual flashing? We’ve got some issues with the manufacturer and they screwed up when applying the labels. Labels don’t match what the BIOS says.

We have 5+ sites and we’re a large organization with many techs. It would be as simple as putting a comment in the inventory but that’s just not gonna fly as not all the techs pay attention.
