How to configure Proxifier to bypass corporate proxy?

Question

Squid

The crux of the problem is this. I live in a hostel, where you can’t get your own wired Internet, but there is free wi-fi provided by the lyceum. The catch is that porn and toys are mercilessly blocked so that the kids learn and not watch all sorts of nasty things.
The second problem is the lyceum. Therefore, the option to approach the system administrator with a box of beer will not work.
In general, only VPN or proxifiers remain. Because I'm too lazy to deal with VPN, so I decided to try ProxyFier.
But I didn't quite understand how to set it up. There are a lot of guides on the Internet for adding a proxy, but I did not find any guides for bypassing it.
How to set up a chain so that programs work through a lyceum proxy?
