I don't know of any way you'll be able to do this. Could you describe a bit more about the system you have in place? You may be able to trigger a script of some sort that could open the requested document.
Business have couple of confidential encrypted documents which are physically located in drives. So the requirement is need to provide hyper links to corresponding documents, subsequently, dashboards would use by business users. When user clicks the hyper link, respective encrypted document should open and system prompt for encrypted document password which user needs to pass in order to open the document successfully.
