When i do nslookup the server use 10.0.0.8 which this is DNS from VPN interface, how we can change primary dns used so the server will lookup DNS to primary interface (192.168.100.1)

Hi,

In general, we can change the dns querying by changing the priority order of NICs, use powershell cmdlet such as Set-NetIPInterface with parameters -InterfaceIndex and -InterfaceMetric. However, the query order is affected by multi factors, including group policy, registry etc.

Below articles just for your reference.
