2node, 2 nic

I am attempting to deploy a 2-node, configuration with 2 nics per node. In the deployment wizard I am prompted for a 2nic or 4 nic config, I choose 2. During validation I get an error that I need to use all 4 nics, is their a bypass for this? or why ask me if I am using 2nic if I can't use 2 nics. I'm stuck at this point.

Thanks,
