Hey everyone, I need some help with something.

I live in Turkey and I've been having trouble connecting to Discord. I saw that I could connect using ZeroTrust, but unfortunately, my internet provider has blocked DNS settings. Right now, I'm using someone else's ZeroTrust, but as you can imagine, I'm not too comfortable with it, and I'm hesitant to ask them how they set it up. So, in short, how can I change the DNS settings?
