Hi Evil_Fischi
Not directly in the scene capture 2D component, but you have some options available inside the Scene Capture 2D actor, below in the Scene Capture tab, you can hit the arrow to display more options, here you can enable/disable lots of features like bloom, translucency, decals, fog, etc that you do not need capture,
I afraid this tab is not exposed directly into components, but you can access it from c++ easy and modify this variable: FEngineShowFlags ShowFlags;
