Hi,
For Windows 10 home version, we even have not corresponding option to defer Windows feature update. It is not like Windows 7 as Windows 10 have changed it's architecture to prevent make more changes on Windows Update.
As you upgrade from Windows 7 to Windows 10, so if you want to reinstall Windows 10, the only official is download Windows 10 1909 ISO image to install. Or you need to reset system through Settings\Update&Security\Recovery\Reset this PC. It will keep your personal files.
If my information is useful for you, please mark it as answer.
Bests,
