Ethernet not working with PCIe NIC on AMD

CPU: Ryzen 2600 Mobo: MSI X470 Gaming Pro GPU: Radeon RX 480 PCIe NIC: Intel E1G42ET Dual-Port Gigabit

I can't get ethernet to work on my system, my mobo is an MSI X470 Gaming Pro, and my PCIe is an Intel E1G42ET dual-port gigabit server adapter. I've tried the Mausi kext, no luck. Tried the SmallTree 82576 kext, still no luck. Tried this kext I found digging through his repo, and still no luck. Hell I've even tried a USB adapter from amazon basics, and still no luck. I can't use the onboard ethernet as it had a short life (killer networking adapters can go straight to the trash). In Network Utility, I get options for interfaces, yet they don't do anything. I then tried setting an IP address on the interface, however the command line returns that the interface doesn't exist.

I'm out of options at this point, personally.
