Is it possible to suppress a Shape Effect via a Shape/Mask Role ?

[Subpath]

Is there a way to suppress a Shape Effect via a Shape/Mask Role ?
If yes which role should be used ?

For Example i have a few Lines with a Shape Effect applied in this case
a outline zigzag Shape Effect. But i would like the area below the
letter to be flat.

In the image I used a clipping mask with the letter. But I thought
having a way to suppress a shape effect would offer further
possibilities.

@Subpath No possible for this effect. A few effects use a mask for intensity, but not in this case

Thank you, I just wanted to know. I know that you can control
the intensity of some effects using a mask.
