Possibility to disable layout css globally

Hello,

in DS you can "disable layout css style" when you are in "manage display" view for example for a content type, but you can't disable the css classes in page manager when you are in the layout setting.
It is possible to add a feature to disable ds css classes globally or add the same option in page manager layout settings like the one in content type?

Or do you know a different way to disable ds css classes. The reason why is there are conflicts between ds css classes and bootstraps classes.

Thank you
