Generic x86-64 Install on NUC - WLAN + LAN for 2 IP Addresses?

After troubleshooting the install of the Generic x86-64 install on a 7th Gen NUC, I discovered in one of the other posts that disabling WLAN in the bios can help. Sure enough, that fixed the first run issue I was seeing and now HA is running on this device as expeted. ← This should be listed on the official instructions as a workaround for issues on first boot!

Now that I have HA working, I do like the idea of having two IP addresses for this box, so is there a good known way for this work?
