No you can't, because the software industry spent a lot of effort encrypting DNS and HTTP so that intermediaries can't tamper with or spy on it.

I am a parent. The devices my child uses have root certs that allow me to decrypt traffic that must pass through my proxy to be relayed to the internet. Voila. Problem solved with current tech.

You're lucky the browsers eventually relented and allowed custom root certs. That was seen as a vulnerability and almost patched.
