There are several reasons why you can not install or run Snow Leopard on a new iMac
The main one, is that Snow Leopard does not support the new Mac’s hardware.
see > Use the Mac operating system that came with your Mac, or a compatible newer version - Apple Support
You can't. A Mac running Catalina is too new to boot Snow Leopard.
