Hi

These IPs can be blocked via Luci - Network - Firewall - Traffic Rules.
Here's an example for Cloudflare DoH:

thanks it work fine,

i also block dns ||cloudflare-dns.com as firefox switch to cloudflare dns when ip is blocked.

I know this is resolved and it is good to know how to use your devices other features, but for others that click on this link in the future:

You can just turn off DoH in Firefox (as seen in your screenshot). And it says it will use your default resolver. Which will be your DNS router settings.
