Lumen in fast moving train?

In my experience, the player is sitting in a moving train, sightseeing the world. Lumen Illumination inside the train is flickering like hell (as expected for a fast moving object). What can I do to get clean lightning inside the train? I know that Lumen is composed of global light cache (static in the world, probably main source of flickering here) and screen space final gathering. Can I somehow disable the global cache on selected objects/entities? Theere is an entire town outside, I can’t globaly use more brute force methods, frametimes would explode.
