Messing around with ASM2464PD symbol and footprint
The ASM2464PD is meant for USB4 (or Thunderbolt 3 and USB3.x too, afaik) to NVMe SSD enclosures, and the ASM2464PDX is meant for USB4/TB to general PCIe devices such as GPUs. I've read that the PD one also works for general PCIe devices but it's not officially supported. An AX210 wifi card worked on an ASM2464PD (non-X) enclosure for me, haven't tried GPUs yet.
