Yes, you can. Yes, you can. But it is not recommended that macOS can be compressed to a minimum. It only takes up about 36Gb of space.

If you delete the macOS, you have to reinstall Windows, and then you have to install Windows through EFI, which will be more troublesome to drive. Once your window is broken, you can't fix it directly.

And Mac doesn't have BIOS, so it's still not recommended that you delete macOS.

Actually, macOS is very useful. There will indeed be much less software than Windows, but most of the commonly used ones are still available. Gestures or something are still very useful.
