" do you mean the routing table in the OS of the machine. "
Not, really. When you set up a NIC, you define a subnet and a default gateway for it. Windows will create itself all necessary routes. You will be able to reach any address in those subnets right away. However for addresses outside of those subnets, Windows needs a default gateway and here’s the dilemma. Each NIC has its own default gateway, but there may be only one default gateway in a system as a whole. Therefore, Windows will pick one of those NICs and use it for those addresses all the time, that is unless it is told otherwise. Windows Server or Windows 10 makes it possible to set up load balancing to use multiple NICs. Windows 11 does not support it. But, yes, you can create static routes for some specific addresses or address ranges where you indicate the NIC to be used.
