Boundary conditions when a pde degenerates to lower order

In a pde module, suppose the default form has a second derivative in space. In the boundary conditions, there are terms related to the first derivatives in space. What if the user sets the coefficient in front of the second derivative in space in the bulk to be zero, then the first derivatives boundary conditions are redundant. How will the software deal with this situation?
