Why flickering in emissive material?

Hi friends, I maded this video and used emisive material in a floor line light. The flickering is a disaster as you can watch. Is there any way to solve it?
Thank you.

It’s a known Lumen limitation, that it doesn’t play well with strong Emissive materials (yet). I think there’s either Actor Level Switch or Shader node to make that material non emissive for GI and I think Lumen respects that. I just don’t remember where it was.
