How to set CPU performance to max(3000MHz) on TrueNAS core?

Linux commands like cpupower, cpufreq-set are not available on FreeBSD.
I tried the command powerd with script from https://gist.github.com/dreamcat4/640f40331719d3858483 but the script(./cpu-speed.sh 3000) is not able to set the CPU frequency to 3000:

root@truenas[~]# ./cpu-speed.sh 3000
dev.cpu.0.freq: 1900
dev.cpu.0.freq_levels: 1900/1805 1600/1480 1200/1072
root@truenas[~]#

root@truenas[~]# powerd -n hadp
powerd: powerd already running, pid: 51667
root@truenas[~]# sysctl dev.cpu.0.freq_levels

dev.cpu.0.freq_levels: 1900/1805 1600/1480 1200/1072
root@truenas[~]# powerd -a max
powerd: powerd already running, pid: 51667
root@truenas[~]# sysctl dev.cpu.0.freq_levels

dev.cpu.0.freq_levels: 1900/1805 1600/1480 1200/1072
root@truenas[~]#
root@truenas[~]# cat /etc/version

AMD Epyc Embedded 3351 has a Base Clock of 1.90GHz and a Turbo Clock of 2.75GHz. So you cannot set to it higher clocks then supported.

Only clocks as reported are choosable:
"dev.cpu.0.freq_levels: 1900/1805 1600/1480 1200/1072"
Highest here is 1900MHz which your CPUs base clock.
