If the device e.g. your smart TV, has an option for it, then you can do that. If it hardcodes a bunch of resolvers, you can't do much about it.

- darkhorn 4y agoIn Android you can disable it or point it to your own DoH. Classic DNS resolvers can have same "hardcoded" problem.
- est31 4y agoWith classic DNS resolvers you can modify the responses on the fly as long as you provide the box its network. Not possible with DoH.
