How to bypass fortinet fortiguard web filtering??

So umm my college has blacklisted quite a few websites and apps so as to promote productivity and a studious environment. They are using fortinet for this task.

Unfortunately this also includes steam, epic games and even the riot client. I cannot access any of them and cant play any games on my dorm wifi. I was hoping to gain help for bypassing this even if its just for steam epic and riot. I can always use my mobile data connection to access the other websites but playing valorant on mobile data hotspot leads to ridiculously high ping in the neighborhood of like 150-250 ms. Can anyone help with this??

keep in mind I am not an expert or even well versed in networking so please treat me like your parents when trying to explain how things work or how to go about trying to bypass this.
