I think the only way to do it is to edit licenses.licx file manually and remove DataTree.C1FlexDataTree from there. Note, VS edits licenses.licx file automatically when you work with forms and controls in designer. If you close all designer windows and edit licx file manually, your changes will be saved and you can avoid issues. The most common issue with licx files is build error after you updated controls to other version. To avoid it, you can just remove version and public key token information from this file at all. After that it would work with any version. I.e. you licenses.licx file content should look like this:
