Can we set CPU frequency separately for each core (DVFS) in the Jetson AGX xavier NX series?

[gxtzhuxi1]

I have a Jetson NX board which is set to 20W-6core mode with 6 physical CPU cores.
My question is whether we can set the CPU frequency separately for each independent CPU core.
As I check in the available CPU frequencies in the setting as below, can we set the CPU frequency dynamically using DVFS techniques?

    $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
115200 192000 268800 345600 422400 499200 576000 652800 729600 806400 883200 960000 1036800 1113600 1190400 1267200 1344000 1420800 1497600 1574400 1651200 1728000 1804800 1881600 1907200 

I use the setcpufreq program (attached) to set the CPU frequency. But when I check it, the cpu freq of all CPU cores is changed!!! They are totally together bonded.
setcpufreq.cpp (4.5 KB)
Could anyone help me with the freq setting, or let me know if the idea of changing CPU frequency of CPU cores separately is possible or not on Jetson boards?

That’s not supported, sorry for that.
