Your suggestion to limit bind will work for me. I wasn't sure how to tell bind to not listen on an interface. Bind defaults to: listen-on { any; };
I modified /etc/bind/named.conf.options by adding the following line: listen-on port 53 { 127.0.0.1; 192.168.2/24; }; This should restrict bind to localhost and my main network, and should prevent it from attaching to the virbr0 interface. After installing the current version of dnsmasq (2.90-0ubuntu0.22.04.1) and rebooting, it looks like everything is working properly now.
