Inspiron 7791, running Dell Command Update returns Exitcode 2

Currently i'm trying to install our custom company image on 30+ Inpirion 7791 laptops via MDT. The image is a fresh build of Windows 10 IoT Enterprise 2019 LTSC 1809. Unfortunately i'm getting an error when running Dell Command Update v3.1.1.

I start the DCU-CLI.exe via a powershell script with the code below:

$ExitCode = (Start-Process -FilePath ('C:\Program Files (x86)\Dell\CommandUpdate\dcu-cli.exe') -ArgumentList ('/driverInstall -outputLog=C:\Dell_DriverInstall.log') -PassThru -Wait).ExitCode

The result i get is: Exit code 2 meaning "An unknown application error has occurred".

Digging some further in the log i can see this error:

I tried a lot of stuff even installing it manually on a system and running the tool by hand. This doesn't result in an error it even finds 4 driver to be updated. After some digging i tried running DCU-CLI.exe with the /applyUpdates argument and this results in the same result as the GUI. However this only installs a few drivers and looking at devicemanager a lot of device arn't installed.

So i went to www.del.com/support and entered one of the servicetags of the Inspirion 779 machine and i noticed that Dell Command | Update isn't listed but instead Dell Update Application for Win32 is listed. I tried installing this application but is hasn't got a cli.exe and it also results in the same result as with running DCU-CLI.exe /applyUpdates. I also can't find a documentation page like Dell Command Update Userguide for the Dell Update Application for Win32

When Installing Dell Command | Update i saw a readme file that states the Inspirion serie isn't supported:

Supported Systems:
 - Dell Latitude
 - Dell Latitude Rugged
 - Dell Optiplex
 - Dell Precision
 - Dell Venue Pro
 - Dell XPS

Could someone help me out on this?
