Can I reduce min frequency of Ryzen CPU from 2200MHz

I just upgrade my CPU from a Ryzen 5700G to a 5900X, and noticed the idle frequency rocketed from 900MHz to 2200MHz.

As far as I know, on the 5700G the 900MHz was even there with default Proxmox settings, which I believe is "performance" (though I don't know where that's set).

Anyway, I tried both `powersave` and `ondemand`, and the CPU won't go below 2200MHz.

I noticed that the 2200MHz is actually set as the minimum:

Code:
scpu | grep MHz                                                                                                                                          pve1: Tue Jun 28 19:32:08 2022

CPU MHz:                         2200.000
CPU max MHz:                     4950.1948
CPU min MHz:                     2200.0000

Is there any way to reduce this? I found an Ubuntu forum post on this: https://askubuntu.com/questions/1415406/how-to-lower-minimum-cpu-clock-frequency

However, it doesn't really have a conclusive answer.
 
cpupower frequency-info will show the hardware limits for the cpu

Eventually the minimum can be adjusted in the BIOS but i guess your cpu will stay at 2200 MHz.
