Hide Folder Tree special folders?

Windows 11 DOpus Version 12.31 x64
In Folder Tree... How do I hide redundant folder icons: Desktop, Documents, Downloads, Music, Pictures and Videos. These seem to be treated as "System" folders that are protected. I'm hesitant to do much trial-and-error testing on my own.

You can use Preferences / Folder Tree / Contents to hide some tree folders. We'll be expanding this in the future, too.
