Can WinDivert Monitor packets coming from a specific NIC on a machine? Assuming there are two network connections available on the machine for eg. "Ethernet 2 and Ethernet 3"

Yes, each NIC will have a different IfIdx which can be used to filter traffic. Use the Windows IP Helper API to map specific NICs to IfIdx values.
