You can load that support through a NixOS module, though. That's the case for every ARM-based NixOS system to my knowledge, from Apple Silicon to my Rockchip home server.

I think that's going to be very painful though, because Nvidia provides binaries for cuda, cudnn, etc. that depend on one version of libc, whereas NixOS depends on another version of libc.

There's a maintained module for some of those platforms (as long as they're still supported by jetpack 5) https://github.com/anduril/jetpack-nixos
