I run PiHole on my home network, but it's not my default DNS server (for technical and other reasons); I have to configure custom DNS. I'm disappointed that I can't do that with my Roku devices.

I have a specific appliance network, designed exactly for this. My computers don't live on that network, but things that I demand not spy on me lives there.

Adguard is basically the same as Pihole. They run the same way, and are both FLOSS.

But Adguard runs right on my router.

DHCP can certainly do that for you. Set up a reservation, and assign that MAC a specific DNS server.

I'm pretty sure all these devices or apps on those devices configure their own DNS servers these days.
