How do I prevent an emissive material from lighting the environment?

Hello, I have an emissive material which I don’t want to affect the environment with it’s light. I’ve found some options in the details panel of the scene like Affect Distance Field Lighting, but these options are not available when I spawn the mesh through an animation montage. Are there any options to disable this through material settings or inside of the static mesh asset? Help is appreciated a lot!
