> What if you have two different project with different requirements at the same time?

Install multiple versions of Windows SDK. They co-exist just fine; new versions don’t replace old ones. When I was an independent contractor, I had 4 versions of visual studio and 10 versions of windows SDK all installed at once, different projects used different ones.

You can provide custom options to winget, and in there where to install it too (and additional components you need).
