How do I fix this noisy Lumen shadow on my metahuman?

I’m getting a weird noisy shadow on my metahuman, you can see it on the forehead/
face. How can I fix that?

The noise is due to the strand based hair. Strand hair shadows are very difficult to cleanly resolve as they usually rely on dithering techniques. I’m not sure if there is a way to improve it beyond using a different hair rendering technique, like the hair cards seen on lower LODs of the metahuman.
