I couple PiHole with a pfsense router. In pfsense all DNS queries are blocked except to my pihole. This thwarts an IoT device or streaming devices, etc., from bypassing pihole. Then I block known DoH servers on both pfsense and pihole---which is not perfect, since it's really a game of whack-a-mole, but better than not.
