Hello MichaelBenk,
thank you for providing this question.
I am a seasoned Windows expert with almost a decade in usage and support experience and hope to resolve your problems quickly.
Yes that should be possible.
The manager to allow flashing of devices and all documentation can be found here:
https://docs.microsoft.com/de-de/windows/iot-co...
I would however recommend you ask further more specific questions about this more admin orientated subject in technet instead of here in the user forum:
social.technet.microsoft.com/
If you consider your problem solved it would be very good if you marked the answer which helped you so others can find and use this thread.
If this didn't solve your problem or you need further assistance please answer in this thread and i would be happy to help.
kind regards
F. Grobusch
