Upgrading to JetPack 4.6 to use Kernel 4.14+

I have a large dataset stored on external devices using the BTRFS file system. In order to handle the volume of data, I am using ZSTD compression on the filesystem, however, support for this compression method was only added in Kernel 4.14.

JetPack 4.6 only uses kernel 4.9.

I wanted to ask if anyone has had experience upgrading the kernel on the Xavier boards and about the compatibility with the CUDA drivers. I don’t want to move over to JetPack 5.x yet so any solution staying at 4.6 would be appreciated.

Looks like someone has already started backporting zstd module to kernel 4.9.
