I encountered the same issue

As I understand, TFTP has to run on port 69 and a truenas app can’t access a port that low

I presumed the solution was utilizing the built in truenas tftp server and aomehow hooking NetBoot I to that, but this is a wild guess.

It seems the truenas app isn’t explained very well, I could not find a mention of what’s up with port 69
