HDRI Environment Medium - Possible to add noise?

[Mayahi]

Wondering if this is possible - to add a noise to the medium within the environment tag on the hdri?

If it's not possible, whats the most efficient/lightweight way to achieve this. I do this in Redshift all the time with an RS environment and its super fast/quick to use. Wondering if I can get it working in Octane.

Off the top of my head, I would do this. Just click on the Node Editor icon in the HDR/Texture Environment attribute panel. I used a Multiply node to integrate the noise, but you can use any node that will suffice...
