Among all 45 Xavier NX-compatible carrier boards in the catalog, the distribution of Ethernet port counts tops out at 5 — one board (the RTSO-6003-VP3.0) — followed by one board with 3 ports, and eleven with 2.

Runner-up if you want fewer ports in a smaller board: the HZHY-AI600 lists 3 Ethernet ports (GbE) for Xavier NX/Nano. hzhytech.comhzhytech.com ↗“io.ethernet_ports=3”
One caveat: of the 45 Xavier NX-compatible carrier boards, 39 list an Ethernet port count; the value is not listed in the catalog for the remaining 6, so I can't rule out that one of those unlisted boards also matches or exceeds 5 — but among every board with a stated figure, the RTSO-6003-VP3.0 has the most.
