So in DR the F5 is not in play. The DNS server in question is external to the F5. You could block with firewall or switch level ACLs, you can put the DNS server behind the F5 and control access via up/down the associated Virtual Server you create, or just architect this more cleanly. Really sounds like Production and DR are configured way differently.

You may need to provide an architectural diagram if we are still not understanding your use case.
