how enable intel pt in pve8.2?

[wh0am1i]

Hello, everyone
I have a question I'd like to ask:
I have a computer with a 13900HK CPU, and I installed PVE 8.2. I want to use Intel PT in the virtual machine of PVE. How can I achieve this?

Currently, I have tried the following methods:

modprobe -r kvm_intel 
modprobe kvm_intel pt_mode=1 
cat /sys/module/kvm_intel/parameters/pt_mode            # can't set 1

help me, Please

you need to add intel_pt as cpu flags args into vmid.conf
like : https://forum.proxmox.com/threads/syntax-of-args-in-vmid-conf.91439/post-398771
but seems broken :

I used args:-cpu host,+intel-pt, but when running it, I got the following: warning: host doesn't support requested feature: CPUID.07H:EBX.intel-pt [bit 25]
