Static Noise on Metahuman Hair

Hi, I have a weird issue with MetaHuman hair. There’s some static noise in the hair, and I’ve been trying to follow the guide from the Unreal Devs Forum, but it doesn’t seem to fix the problem. Since there’s still an issue when using Temporal AA, I’m only using Static AA at 32. Does anyone have an idea where the noise might be coming from? Thank you!
