We are looking to be able to find/display the serial number/service tag of the underlying server hardware. After working with support it was determined we needed to open a feature request for this information as it is not currently available.
We use LionGard for source of truth overviews of our customers environment; when doing risk assessments or project preparation, having this information front and center is invaluable.
I can see similar information for VMWare ESXi with metric : VMware ESXi: Host Hardware Serial Number
If it is possible to gather this information from Hyper-V and include it in the Data Print/JSON it would be very useful, and also consistent!
