I don't believe that there is an option for this in Visual Studio. Even setting the TabStop property is not excluding the control from the design-time Tab Order. Nevertheless, this functionality is connected to Visual Studio and perhaps it would be better to ask if there is a way to achieve this in their forums.
Should you have any other questions do not hesitate to ask.
