How to stop checking for updates?

I’ve seen it here that you can try and block Topaz plugs from checking for updates by setting a firewall rule. Can anyone explain how to do this using Windows Defender?

My Topaz plugins have expired, and I’m not interested in renewing. But I still want to use the version I paid for without a nag every time I open it.
