You are missing information to determine if UASP is used/supported
1 - Check to see how it is detected.
Code:
--------------------
tc@Pi4-aarch64-Devel:/mnt/build/aarch64$ lsusb
Bus 002 Device 003: ID 04e8:4001 Samsung Electronics Co., Ltd <<-------
this is my SSD, sitting on Bus 002, Device 003
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 1a86:e050 QinHeng Electronics
Bus 001 Device 003: ID 1a40:0101 Terminus Technology Inc. Hub

2 - To examine the drive capabilities
Code:
--------------------
tc@Pi4-aarch64-Devel:/mnt/build/aarch64$ lsusb -v -d 04e8:4001 | grep -i
interface <<-----enter the xxxx:xxxx device identifier shown from lsusb
