Any way to disable Design Mode in Writer?

I understand that Design Mode can be turned on and off but is there a way to not only turn it off but also prevent anyone who receives the document from turning it on?
When you make the whole file read-only, you can still use the form and edit the database behind the form.
I want to be able to prevent people from being able to make changes to Writer forms using Design Mode in forms I ask to be filled out. I found that making the file Read-Only accomplishes the goal but that is weak protection.
