Changing wallpaper

So, my school changed from personal laptop to ipads, i opted to buy a personal ipad and use it for school and entertainment at home. However, our school borrowed the iPads for a while to “download the school books” and i got it back, it had a ton of restrictions, most dont affect me directly but i think it isnt fair to change the wallpaper on a device thats mine. Now im stuck with one low resolution logo of the school on my personal ipad. Is there a way to remove or change the wallpaper without having to bruteforce the MDM?
