Compact PCIe to Eth

The tachyon pcie docs mention a board for this use case. This board has a decent amount of dead space. I’m wondering if anyone’s found a more compact version that’s off the shelf?

My alternatives are adding an m2 adaptor board and then a m2 to ethernet like this. I would like to avoid the extra cable if I can.

these get detected by our tachyon but the Intel IGC driver is missing so haven’t been able to test them yet Amazon.com: Ableconn M2NW108BM 2.5 GbE Base-T M.2 B-M Ethernet Module (Intel I225 Ethernet Controller) - Right Angle RJ-45 : Electronics
