My need went well beyond what @zzzhouuu did (thanks it was essential!) - with that invaluable breadcrumb trail and my mate claude i got a solution that:
- uses github workflows to build truenas sysext environment (using free runners)
- auto checks for new nvdia open drivers and runs workflow
- lets me run a workflow for any truenas build or nvida driver version using a UI
- injects displaymodeselector in sysext at install time (not included in package as it has license agreement that prevents distribution)
- defines MIGs at each boot using systemd service in the sysext (WIP)
- assigns one compute MIG UUID to all containers with UUIDs cofnigured (WIP)
- auto re-application of sysext package on truenas update (WIP)
and i got this far after 72 hours…..
yes this is a blackwell 6000 pro workstation card with 4 MIGs (2 compute MIGs, 2 GFX migs)
@HoneyBadger please can ix-systems consider includig 580.x in the fall release so i don’t have maintaing the github repo i just had to create, these are the open drivers so should work just fine for my need. 
oh an please include all normal user mode tools except displaymodeselector which i know you cant include (and include persistencd daemon)

this method works to assign the MIG to a docker container
