Sure, you can have it call netsh:

::// Below sets a network card called "Local Area Connection" to use 192.168.0.1 and 192.168.0.2
::// Use netsh interface ipv4 show interfaces to get the "name" of the LAN connection(s):
netsh interface ipv4 set dnsservers name="Local Area Connection" static 192.168.0.1 validate=no
netsh interface ipv4 add dns "Local Area Connection" 192.168.0.2 index=2 validate=no

::// Below will set the interface back to getting the data from a DHCP server:
netsh interface ipv4 set dnsservers name="Local Area Connection" dhcp
