Trouble building PREEMPT_RT for Jetson Orin Nano Jetpack 6.1 R36.4.0

Hi,
Please enable the config to set tick frequency to 1000Hz:

CONFIG_HZ_1000

And after executing the steps in Kernel Customization, $ sudo ./apply_binaries.sh is not required and please run initrd command to flash Orin Nano developer kit.
