I need to trigger a static mesh to disappear, I'm trying to use Set Visibility with a Static Mesh Component but how do I change the Default Value?

Sorry, I meant the default value in the blueprint. I have a Static Mesh Component that’s suppose to reference the mesh I want to disappear when the actor enters the trigger box, but it’s not letting me change the value.
Hopefully I’m not going about this the wrong way.
