TMSFNCDataGrid - disable combobox

Is it possible to disable a combobox column?

Code like this did not work:

GetInplaceEditorProperties(Sender: TObject; ACell: ...
(AInplaceEditor as TComboBox).Enabled:=false;

(AInplaceEditor as TComboBox).Visible:=false;

This is typically done with the ReadOnly setting, at column level, or setting editing to false, or OnCanEditCell, to avoid editing all together.
