@Kristof Boeykens , Based on my research, I find there's a setting named "Show device's name on MHS" may be helpful. When the setting is set to True, we can view the device's Intune portal "device name" property from the Managed Settings app. We can configure it in app configuration policy to see if it can help. Here is a link with more details for the reference:

Hope it can help.
