uProf not supporting PMU events on Threadripper 3990X

Hello everyone, I'm trying to profile L3 related events on Windows 10 machine with Threadripper 3990X. I use AMDuProfCLI, when I type AMDuProfCLI info --list pmu-events, the terminal return "No events are supported." However, according to the manual: "NOTE: L3 PMU events are supported only on Windows and only on Family 0x17 processors. ", my processor should support these L3 related events, following is the content when I run lscpu in WSL:

Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
Address sizes: 48 bits physical, 48 bits virtual
CPU(s): 64
On-line CPU(s) list: 0-63
Thread(s) per core: 1
Core(s) per socket: 64
Socket(s): 1
Vendor ID: AuthenticAMD
CPU family: 23 (This is 0x17 in decimal)
Model: 49
Model name: AMD Ryzen Threadripper 3990X 64-Core Processor


I wonder how can I use the L3 related PMU events, is there something miss in BIOS I need to setup?
