TYPO3 DCE remove “Select & Upload Files” button

I’m using TYPO3 v12 and DCE (Dynamic Content Elements) extension.

I have managed to remove the “Select & Upload Files” button from the standard content elements (Image, Image & Text, Media) with the following lines in TSConfig:

TCEFORM.tt_content.image.config.appearance.fileUploadAllowed = 0 TCEFORM.tt_content.assets.config.appearance.fileUploadAllowed = 0

Unfortunately, I cannot find a way to remove the upload button within new elements created with DCE (Dynamic Content Elements) extension. I tried to follow the pattern of:

TCEFORM.[TABLE].[COLUMN].config.appearance.fileUploadAllowed = 0

… but with DCE it’s not as straight forward, it seems to be more “nested”.

I’ve tried different combinations but without success.
Maybe there’s another way? Directly within DCE or perhaps completely elsewhere?

I looked all over, but cannot find any answers. I only found a way to disable the “Select & Upload Files” button for each Backend-User, but I would prefer to remove it globally and not have to think about it each time for each (new) user (group).
