How to install windows 10 in Mac Pro 13 inches M2

You can't. There is no production version of Windows that runs on an M2 Mac. And Boot Camp does not run on it either.

Install Windows 10 on your Mac with Boot Camp Assistant - Apple Support

Above is correct.

Microsoft Windows 10 and Windows 11 are available for Intel x86-64 processors, and for Qualcomm Arm processors.

You will here need the Windows version that works on Arm processors.

Microsoft does not sell and support Windows on Arm for use with Apple silicon computers.

You can run Windows remotely, but there’s no commercial, supported option to run Windows on a current and non-Intel Mac.

Put differently, host Windows remotely, or ask Microsoft. They’re not (yet?) selling what you need here.
