@E24 if you're looking to block most ads and 'trackers' on Android, then generic DNS endpoints from AdGuard, Mullvad etc should do the trick.
If you want above but with more comprehensive blocking and control, you can't go wrong with NextDNS.
If you're looking to hide your IP address from websites and your ISP you need a VPN.
If you're looking to do both (hide your traffic and block ads), you will be well served by a VPN that does content filtering (Proton, IVPN, Mullvad etc). It's both what's recommended by the project and what will give you least headache.
If for some reason you want both VPN and Encrypted DNS (such as NextDNS) you can do that too.
