Wouldn't a hosts file or a local DNS[1] or VPN[2][3] with hosts file support solve that without having to switch software ? I'm using Netguard on Android devices I don't want to root and it's been good. Plus it does per-app firewalling as well.

https://getintra.org/ is the only DNS client I know of that doesn't leak DNS connections over TCP, most other DNS apps (including the 3 mentioned here) do. Blokada is marked with anti-features tag by f-droid for telemetry: https://gitlab.com/fdroid/fdroiddata/-/merge_requests/8536 (Note: Intra, though open-source, has telemetry in it too). Disclaimer: I co-develop a Intra fork.
AFAIK personalDNSfilter lets your route the DNS however you want. Not that it matters too much to me. I'm not trying to have airtight privacy, I just don't want to be buggered by trash. I'm interested to see your fork, though.
