Correct 20Gbit USB 3.2 is not supported on the FW13/16.
Thunderbolt up to 40Gbps is supported on the FW16. (According to FW docs, I have not tested it)
So, get a Thunderbolt device and not a USB 20Gbit device.
Note, its probably not called Thunderbolt, its USB 4.0, but it is compatible with Thunderbolt devices.
Note: due to overheads, although it says 40Gbps, you only get about 27Gbps of data transfer.
Note: 40Gbps devices also get pretty hot.
