Preventing Landscape Grass from Stretching when masked out of RVT?

I want my grass mesh to not render at all when an object/actor is rendered to the Runtime Virtual Texture above it. Currently, when there is an object, my grass still renders, but it is pushed down under the terrain and hidden, this works in some cases, but also causes an ugly stretching artifact on the grass bordering the intersecting object.

Is there a way to make the grass not render at all instead?
