How to set EMC frequency as a value between EMC minimum and maximum frequencies？

I want to change the EMC frequency on jetson xavier nx and refer to this website. Jetson Orin NX Series and Jetson AGX Orin Series — Jetson Linux Developer Guide documentation
To set static EMC frequency, enter the commands:
$ echo 1 > /sys/kernel/debug/bpmp/debug/clk/emc/mrq_rate_locked
$ echo 1 > /sys/kernel/debug/bpmp/debug/clk/emc/state
$ echo <emc_freq> > /sys/kernel/debug/bpmp/debug/clk/emc/rate

  • Where <emc_freq> is a frequency value between EMC minimum and maximum frequencies.

I tried these commands and set <emc_freq> as 408000000, but when I checked the emc rate, it remained as the maximum frequency (1600000000). I want to know whether I can change the EMC frequency as a value between the minimum and maximum frequency. If it is possible, how to do?
Thanks.

better clarifying which jetpack version you are using here

My jetpack version is 4.4.1 [L4T 32.4.4]

You better check the JP4.4.1 L4T doc - Jetson Linux Developer Guide (downloadable version)
