Xavier AGX - M.2 Wifi card dissappears when M2. SSD connected

I have an Jetson Xavier AGX dev kit here, and everything was working fine with an Intel 8265 wifi adapter attached to the M2. slot on the bottom of the device. Last night, I attached a M.2 SSD to the M.2 slot on the flip side. “Western Digital 500GB WD Blue SN550 NVMe Internal SSD - Gen3 x4 PCIe 8Gb/s, M.2 2280, 3D NAND, Up to 2,400 MB/s - WDS500G2B0C”

Now, the SSD works, but the WIfi card won’t show up. I don’t think it’s a hardware problem, because the Bluetooth connectivity provided by that same card still works. So it’s some sort of bus conflict perhaps on the PCIe bus? How would you diagnose or correct this?
