Experiencing Firefly Flickering in Movie Render Queue

Hello,

I am currently rendering out a shot and have been experiencing these firefly flickers in my renders.

I’ve done some research and have found this is related to Path Tracing Reflections. However, I haven’t found a clear cut answer/solution to this problem. I’ve tried the console command:

r.RayTracing.GlobalIllumination.FireflySuppression

But it’s not working.

Here are my AA settings as well:

Any help at all would be very much appreciated!!
