> The Raspberry Pi also has Pi-Hole installed which I configured to block all IPs and domains being used by the IP cameras thereby limiting its access to local network only.

You might have to be careful here. My understanding is that PiHole is just a domain lookup blocker so it won’t block a device which phones home with a straight IP address.

Happy to be corrected.

You are correct. Sorry, I forgot to mention that I also have OpenVPN setup on the Raspberry Pi and the IPs are blocked using firewall rules.

Indeed, if you control over DNS you have to advertise your own DNS server than blocking outgoing DNS requests for everything except you nameserver (UDP and TCP).

Sadly DNS over HTTPS takes this control away from you.
