Dell Command Update CLI - System automatically restarts without using /reboot

I am using dell command update's CLI in a system setup script. I install a bunch of software, drivers and windows updates and then do a restart at the end of the script to flush all of it through. The documentation for DCU CLI states that if a reboot is required, it won't restart on its own UNLESS the /reboot option is specified.

I have been going through *** trying to find someone at dell pro support to actually tell me why my system restarts. Nobody there seems to actually want to try to fix the issue, only to tell me "that sometimes when a driver is installed it needs to restart". No duh. The GUI doesn't force a restart unless I tell it to. The CLI is no different. Nobody there understands it and at this point I think they aren't going to even contact engineering to see if this is a bug (I never get any emails from them on this ticket unless Is specifically ask them).

Is this a bug? This kind of kills my script. Due to bugs in dell drivers (not installing if .net 4.6 is installed) and our software (which requires .net 4.6) this makes me manually do this, which for like 75 systems is a pain.
