I'm not sure there is, I think there's some advanced AMD BIOS settings EFI file floating around but I think it still has the same options.
Are you using the latest version of the BIOS?

If they haven't changed in the last decade, it's basically just 2 USB network adaptors stuck together. So it probably would still work, but I'd also prefer the modern solutions anyway.
