Feature request: Use your own DoT/DoH Provider

[iluvatyr]

What's the feature 🧐

I was reading the Docs about possible : DNS-Settings

I just wanted to ask if it would be possible to implement something to point to your own DoT (NextDNS Adguardhome, ControlD), or is there a reason why it is not supported right now?
