Sounds and Forge

So i purchased the Syrianscape Sounds on Forge literally right before FGU released its own functionality so my purchase was a complete waste of money. I am slightly OCD so i would like to ensure that Forge doesn't continue to download the mod for Syrianscape and make my extension list a bit cleaner. Is there a way to stop being subscribed to something on Forge so i don't get it resinstalled?

Go into your Forge "Inventory" and click "Disable" next to the extension and then run an update in FG.
