NVIDIA's L4T delivers an Ubuntu-based distribution with a customized kernel based on version 4.9/5.10. The way the kernel is configured and deployed is different from a desktop Ubuntu image with two notable differences being the list of kernel modules included in default configuration and the way a new image is flashed.

And while it is possible to rebuild and flash a new kernel image the procedure can be perceived as challenging and shall be performed with extra caution.
This guide comes with a script that allows to modify the kernel modules with Librealsense2-related patches without replacing the kernel image. The script has been verified with **Jetson AGX Xavier™** board using L4T versions 4.6.1 (Sept 2020) and 5.0.2. Scroll to the end of the guide for details.
