Server core - assign static IPs on command line

First determine your interface names for multiple NICs:

netsh int ipv4 show interfaces

Next assign IP details to the interface name you require:

netsh interface ip set address "Ethernet1" static 192.168.99.101 255.255.255.0 192.168.99.1
netsh interface ip set dns "Ethernet1" static 192.168.99.2
netsh interface ip add dns "Ethernet1" 192.168.99.3 index=2
