School requires CA certificate for internet access. Will use of VPN or proxy tunnelling prevent this? [closed]

My school uses a thing called Cyberhound. It filters websites and stuff. In order to connect to wifi, it requires students to use their given username and password. After you are connected, you must install a CA certificate provided by the school to be installed under Trusted Root Certification Authorities (on our personal devices). If not installed, every websites are blocked and prompts us to install the certificate. I did not sign nor read anything saying that they will do this.

I did some research and found out that there is a possibility that users with the certificate can intercept and decrypt any SSL/TLS connection on the local network. Is there any ways to access the internet without the certificate? I heard it is possible with VPN or proxy tunnelling through unblocked ports.
