Hello, De Palma Francesco.
Welcome to Microsoft Community!
I understand that you want to install Windows 10 system on Surface Pro 9 with an Intel SQ3 processor (arm) via the SCCM method.
I'm sure you're aware of the common way of installing Surface systems, where we tend to get the image file through a dedicated Surface Recovery Image site. But that way you end up getting Windows 11 system, so that's why you would install Windows 10 via the above method.

But apparently, the problem you are experiencing is due to the difference between the Arm system architecture and the X64 system architecture. The processor model of this Surface Pro 9 does not support the current installation method.
Surface Pro 9 with Intel SQ3 processor (ARM architecture) only supports Windows 11, version 22H2 and later. Attempting to install Windows 10 on this device may result in driver compatibility issues and other functionality issues.
