Grabbed a realtek 8125B 2.5Gbps NIC for my X86 but it's not detected, what do I do?

Hardware Questions and Recommendations

Just bought this https://www.amazon.com/gp/product/B08V1HG47H/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 for my x86 router. Installed it but don't see any packages that would work for it. What do I do?

If this is not easily doable, I'd be interested in grabbing a different NIC, I just don't know what would work for OpenWRT easily that's 2.5Gbps+ and PCI Express

The best approach would be testing the master branch with kernel v5.10, but that requires building from source and enabling CONFIG_TESTING_KERNEL=y.
