DoHoT on Pi4 router

Please advise me on what documentation I should follow to achieve DoHoT on the Pi4 Router. I would like to encrypt ALL my dns packets.

The only article I found on here was one on tor.
https://openwrt.org/docs/guide-user/services/tor/client
Then of course a cloudflare article
https://developers.cloudflare.com/1.1.1.1/other-ways-to-use-1.1.1.1/dns-over-tor/

Just popped in to say hi and googled what DoHoT was.. Good Luck, It sounds interesting.
