Do you know why they need a SVP serial number? Are they looking for the part number?
I tried viewing a few asset hierarchies in Salesforce, and I don't see specific serial numbers tied to the SVP (it shares the asset serial).
There are a few Windows commands that may get them the baseboard information if that is what they are looking for:
Powershell: Get-CimInstance -ClassName Win32_BaseBoard
Terminal (may be deprecated): wmic baseboard get Manufacturer,Product,SerialNumber,Version
