You are probably right about that. My org (US Govt) blocks encrypted DNS. But they kind of block everything.
It should be. DoH is more popular and also the default on pretty much every system or browser.
DoT is designed for system wide use. It is actually a better, cleaner protocol. I wish Windows supported it. DoH is a mess.
You can disable the profile easily too in the settings, but I am not here to keep on annoying you with the same stuff. I stopped using encrypted DNS on my iOS device and use it on my Firewall network-wide, as I faced the same issue as you. Always got a notification, that I am connected to a network that forbids encrypted DNS, even tho it was my home network and not the case.
What router are you using?You can disable the profile easily too in the settings, but I am not here to keep on annoying you with the same stuff.

Speedport Smart 4 but I doubt that you know it. After all, I only get the notification but nothing gets blocked.
Definitely not familiar, I'm assuming it's German. iOS seems sensitive to some router configurations, so I was curious.
Read some posts on a forum and they said that it was somehow an iOS 14 related issue. No idea, but as I said it isn't really a big deal, as I can use encrypted DNS normally.
VPNs are tougher since they can use various ports and there are a lot more IPs to block. But they can be blocked.
As @blackice said VPNs are harder to block, as for example the OpenVPN protocol uses the port 1194 or 443 if I remember correctly. So basically two ports that would need to be blocked. Another method would be the blocking of all the individual IPs of popular VPN providers.
