Word of warning - I don't know how much you've looked into it yet but depending on your needs from Jetson the Nvidia stack gets really complicated really quickly.
I know people have frustrations with Nivida supplied Jetpack but when you end up trying to figure out how to roll your own support for TensorRT, DLA, cuDNN, etc (on ARM64, of course) many people bail and run screaming back to Jetpack.
