Ethernet port no longer detected after video card change

I swapped video cards (and sold the old one so I can't go back) and now Linux does not see my ethernet port on my motherboard in any way - lspci doesnt show it, ifconfig -a doesn't show it, I had to use a usb ethernet hub to get online.

So far I've attempted switching to an older working kernel, and resetting my BIOS/UEFI settings - I'm not sure the best path to troubleshoot next - I'm considering making a live USB or something to boot to and see if it sees it or not

OS: Gentoo Linux x86_64 - I have fully updated as pat of the troubleshooting process after first trying an older kernel
