How I can delete expired deomain

Too much domains are on server, how can delete expired or not working domains which should not be use for renew or other check by openresty service. Expired domain should not use by openresty service and removed from system. Can you please help how I can do it.

The issue names no file, test, or entry point. Start by locating how domains are stored and how the OpenResty service performs renewal and other checks. Define which expired or non-working domains should be removed or excluded, then verify that they are no longer used by those checks.
