This part is so brief that I don’t know how to start. Is there a more detailed tutorial?

Hello,

You need to download the kernel and apply the change in the kernel configuration.

This is a guide of how to download, build and install the kernel sources Kernel Customization — NVIDIA Jetson Linux Developer Guide 1 documentation

Before to compile the kernel make -C kernel you need to add the line CONFIG_STRICT_DEVMEM=n to Linux_for_Tegra/source/kernel/kernel-jammy-src/arch/arm/configs/tegra_defconfig file

Then you can continue with all the steps to install the kernel.

Thanks a lot ! But I still have a question: While making the NX as the EP, and another device as RC. Which device’s kernel configuration should I change? EP or RC or both?

Hello,

Please can you explain more about what is EP and RC?
