HP Chromebook 11MK G9 EE hack/unenroll

I just graduated and was given my Chromebook by my school. I was told that it would be unenrolled from the school’s domain a few days ago, which it wasn’t, even though others were. Does anybody know of a way to remove the enrollment so I can do stuff and maybe install PostmarketOS?

go to your school and tell them to unenroll it.
