As far as other similar hairstyles there is Cyber Hair by Midnight_stories (RDNA)

As for the exact hairstyle that's in Aeon Soul's (Alpha Seed; Aery Soul) promo, I am pretty sure it is Wild Dreads (at Daz) by Anna Benjamin and ElorOnceDark, and they just customized the material on it to make it look cyber-ish. I say this becaue it has the same thickness and same exact amount of "beads" on it.

Here is the page that has Aeon Soul's promo (which I think you might be talking about but not one hundred percent sure, so please let me know if I'm wrong):
