How to modify Surface Hub 2S Teams display name?

Hi everyone,

We've been asked to change the name that is displayed on the "quarter" teams windows that appears on Surface Hub 2S with Windows 10.

As you can see in this image we have the name MTR displayed on our Surface Hub 2S.

We've tried changing every setting we could find on the Hub, on the M365 Admin Center and through PowerShell commands but we didn't manage to change it.

The only solution seems to reset the device with an USB drive altough it's not optimal as it can take many hours to reset and update.

Can you help us?

Thank you in advance

Andrea
