I use Rethink DNS for this, see (https://github.com/celzero/rethink-app).

Despite it's name it can also block IPs and specific apps from connecting to specific servers. I use it to block all manufacturer and OEM related apps that I cannot uninstall through adb or disable. Very handy for blocking constant Chinese phone telemetry pings, as well as additional network level blocklists for ads (Pi-hole like), completely locally so you can trust it unlike a shady VPN.

I checked out your link; it seems to be a mailing list for a hosts file for telemetry? Why is there no option to just see the file without giving in my email? Not the most private.

I don't this is doing a lot, it only has 18 domains listed and is missing all tracking domains from samsung, motorola, apple, android, etc..
