i mean you could just put an OS on a big enough usb and back it up from time to time, it's funny actually when our school first got laptops was when they were in a rush to get them to students before the possible lockdown because of Rona related stuff, anyways long story short i had BIOS access and i wasn't locked out... plus the guidelines for using the device held you accountable for bricking it but it didn't say anything against booting your own OS hence me running Linux on the machine nothing too crazy i think IT caught on after the first year... though you could just replace the drive, though I think doing what they did now would probably discourage that but man, imagine how cool that'd be to teach as an elective to customize your school laptop and build custom programs
