How to use Jetson nano module's PCIe interface expand gigabit network port?

1. How to use Jetson nano module’s PCIe interface expand gigabit network port? Has schematics design example?
2. Can I expand 3 gigabit network port? And is each port has gigabit bandwidth？

I know of no M.2 PCI express based Gigabit Ethernet modules that fit the Jetson.
Someone had a link for a device that put the connector on an extension cable, which might fit? That still just gets you one gbit interface, though.

If you’re OK with designing your own carrier board for the module, you could of course design the appropriate bus interface/switch to get to where you need to go; I think there may be enough available bandwidth overall for that?

If you aren’t building your own carrier board, the best option is probably something over USB-3.

Yes, I want to design carrier board myself. And want to use PCIe directly.
