Windows 10 version 20H2

The computer in question had Windows 7 on it and there was not an option to uninstall the 20H2 update. So I have reverted back to Windows 7. Is there a way to download and install Windows 10 version 2004? The games will work on that version but not the
20H2 version.

Thanks

Windows 10 version 20H2

I down loaded windows 10 version 20H2 and now many games I play on FB are VERY slow. The games worked ok on version 2004. Question if I down load version 2004 will it override version 20H2, or do I need to remove version 20H2 prior to downloading version
2004?

Thanks.
