Hey RobertG117,
Shroud is set per level via Level > Edit level data... and then "Hide Shroud" to True.
That being said, if you want to disable it for the main game, you'll have to disable it for every level of the main game. (The Hold, Fort Joy, The High Seas, Reapers Coast, The Nameless Isle, The Arena of the One, Arx, Tomb of Lucian ... I think that's all of them).
So:
1) Make an add-on that loads data from Story and targets Story
2) In the level browser (top-right) enable "Show Inherited Levels"
3) Load the above mentioned levels and set Hide Shroud to True
Sincerely,
Kevin
