Enrollment on Intune disabling Android systems app

Hello everyone,

Some explanation first:
We use some handheld Unitech EA520 rugged smartphones with built-in scanners and when i enroll these into Intune, half of the built-in system apps are disabled.
This includes the Unitech scanner service which is used to control the scanner.
When i check under system apps on the device it says "Not installed for this user".

I haven't setup any restrictions ofr the device yet and when i do, there is no possibility to enable these system apps.
Even weirder is that i enrolled 5 of the exact same devices with same android version about half a year ago and they had no issues what so ever.
These are also fully dedicated, company owned devices.

Did anyone experience something similar before, as i am quite stuck ?
