When the platform toolset is set to v140_xp, the symbol BusTypeNvme is not defined in the 64-bit program

When the platform toolset is set to v140_xp, the symbol BusTypeNvme is not defined in the 64-bit program:

At the same time, I noticed that under WIN64, BusTypeNvme is defined as 17. Can I directly set it to 17 to ensure that the compilation passes? Like this:

I don't know if doing this will affect functionality in some cases

Yes, so I'm wondering if the original code was written to prevent future changes to the enumeration value
