AdGuard Home and dealing with DoH
I run Pfsense and am able to block most common DoH services. I’m sure you will be able to configure similar options on opnsense. The best way to do this is a DNS block through AGH and an IP block with opnsense. Firefox provides what domains to block to disable their DoH, https://support.mozilla.org/en-US/kb/configuring-networks-disable-dns-over-https. You can also add these two lists to block most other common DoH services, https://github.com/oneoffdallas/dohservers, https://github.com/Sekhan/TheGreatWall. These lists will work with AGH for DNS blocking and for IP blocking aliases. If you have any Apple devices on your network you can use these domains to block private relay, https://raw.githubusercontent.com/Rogacz/private-relay/main/pr2.txt. I recommend you add these private relay domains as a custom entry in AGH to return NXDOMAIN so that the device shows that private relay is unavailable versus using a NULL response where it will say it’s available when it really isn’t. With these lists added to DNS blocklists as well as IP blocklists I have seen almost no DoH services getting through. The only service that I’ve experienced getting through the rules so far is Next DNS since it uses different IPs depending on what is fastest for your location, making it harder to block. I found a way to discover the IPs for their servers near you and will edit the post if I find the instructions again. Also make sure to completely block port 853 to block DoT. Lastly using these instructions from Pfsense, you can redirect or block all DNS queries that aren’t destined for your AGH instance. The instructions should be transferable to opnsense.

Device has not a single query?
You can also have the pihole block these DoH servers, using this: https://github.com/Sekhan/TheGreatWall/blob/master/TheGreatWall.txt but for applications that have a list DoH IP's hardwired into them, then pihole blocking won't catch those because they connect without DNS lookups. You have to block them at your firewall.
- PSA - Netflix on iOS seems to be contacting 8.8.8.8 (Google DNS) a lot, possibly to circumvent blocking
- Blocklist for DNS over HTTPS?
- How long until Google [and others] use https://8.8.8.8 internally, and hence bypass Pi-Hole?
- Any guide to catching and redirecting DoH traffic?

Adguar home question
Original: https://github.com/Sekhan/TheGreatWall

Android defaults to 8.8.8.8 as secondary DNS with Pi-hole as DHCP server
Another test is android also offers Private DNS under advanced settings if set to automatic it will send requests to google DoH, turn this off and see if that changes anything. You could also add the The Great Wall DoH pihole blocklist to see if that helps too: https://github.com/Sekhan/TheGreatWall/blob/master/TheGreatWall.txt
