Move to the services tab, and Locate DNS Client from the available services. If you wish to Disable DNS Client Service, untick the checkbox of the same. And To keep the service enabled, simply click on the checkbox to keep the tick mark.

Hi Smith_J ,
I'm not sure could that do what I asked? I do not want to disable DNS as that is core component in computer world. The problem is, when you do not have VPN connection established your workstation is sending a lot of DNS queries to the DNS server on your NIC configuration. I was only hunting a possibility to block our internal FQDNs to be sent to external DNS server when VPN is not ready yet.
Obviously our internal FQDNs are not resolvable on public network, but also if someone listening the traffic they could learn our infrastructure (data leaking), but also sometime even user IDs are sent out.
Would be nice to be able to setup a conditional forwarders for our internal domains to known internal DNS servers only. Unfortunately such a term as "conditional forwarder" is an option only on DNS servers and not for DNS clients. But if that could be possible, then when the VPN is not established, those internal DNS queries are not sent out as internal DNS servers are not reachable, until VPN is working again.
