I have an assembly model with multiple configurations. I use equations to suppress some parts according to a defined conditions.How can i disable an equation in a certain configuration?

In order to clarify my question I attach a simple example. In this example I have an assembly model with two parts (Base, Wall) and two configurations (AllPart, BaseOnly). I have also two additional instances of part (Wall).

In the first configuration (Allpart) I want to control the visibility of the Wall<2> and Wall<3> according to the width of the  base and in the second configuration (BaseOnly) I want to suppress only the Walls, That's all.
