My son’s dorm room has a desk with a locking drawer. It is one of those big file type desk drawers with a metal loop for a lock. All the kids use a master lock or something equally sturdy to secure their belongings in this drawer. Drawer is big enough for his laptop, electronics and important papers.
We know kids at other schools where the desks in the dorms can also be securely locked. Check to see if the school you are going to provides desks or dressers with a locking drawer. It is an easy and secure solution and I am surprised reading this thread that all schools don’t provide something similar.
