As far as I can see, there is no way to disable 'allowUploadFolderSelection' in the FileDataObjectManager class. The default init value is 'true' and the allowUploadFolderSelection() method sets it to true as well.
Locally, I have changed the allowUploadFolderSelection() method to
public function allowUploadFolderSelection($allow = true) {
$this->allowUploadFolderSelection = $allow;
}and this seems to do the job. Would be great if you could implement something similar. I basically just don't want the editors to fool around with the folders.
