may I "revert" to Catalina even if the Big Sur is installed from factory?

I received an iMac with big sur but as I use Lightroom, I tested and so many problems that I need to use Catalina instead of big sur. Question may I "revert" to Catalina even if the Big Sur is installed from factory?

iMac 27″, macOS 11.0

No. You can't run a version of macOS earlier than what it shipped with.

Ok Thanks ... bad news for me as I need to use Lightroom CC and it seems is not yet 100% compatible with Big Sur...
