There's a yocto layer for Jetson - which gives you highly customizable OS. Yocto does have steep learning curve, so that's a showstopper.

I remember I tried Yocto, indeed it’s customizable, but when I tested it, its performance wasn’t on par with the stock one, specifically with gstreamer and vp9 encoding/decoding. Maybe it’s changed now though, worth the try OP.
