On Android this is possible: under “Network & Internet” settings there is a field called “Private DNS.” Simply set your own preferred DNS server here.
Adguard has public DNS options that block all advertising, even inside apps, though for state-level exploits as described in this article I’d assume the only way to be 100% sure is to run your own PiHole.
The only caveat I’d add is using the Private DNS function can sometimes break WiFi login pages or cause other network issues - a couple times I’ve found I need to revert to “automatic” to get a WiFi or app to connect properly
