Jetson's config.hz changed from 1000Hz to 250Hz

On the Jetson Orin NX 16g platform, use

sudo apt install nvidia-l4t-rt-kernel nvidia-l4t-rt-kernel-headers nvidia-l4t-rt-kernel-oot-modules nvidia-l4t-display-rt-kernel

After changing the command to real-time kernel, I used this command to query and config.hz changed to 250hz. I was originally 1000hz, is there any way I can modify this

jetson@yahboom :/usr/src$ zcat /proc/config.gz | grep CONFIG_HZ
# CONFIG_HZ_PERIODIC is not set
# CONFIG_HZ_100 is not set
CONFIG_HZ_250=y
# CONFIG_HZ_300 is not set
# CONFIG_HZ_1000 is not set
CONFIG_HZ=250

Hi,
You would need to manually build RT kenel with CONFIG_HZ_1000 enabled. Please refer to

Kernel Customization — NVIDIA Jetson Linux Developer Guide

Jetson/L4T/r36.4.x patches - eLinux.org
Enable RT kernel and CONFIG_HZ_1000
