Enable/disable

Hello, I think a simple question, is it possible to disable a grouop without selecting all the components inside the group? Thanks!!!

Nope. Groups are purely visual elements, they do not have any control over the objects they contain.

Not sure if this is what you are looking for but check out MetaHopper plugin by Andrew Heumann. It contains this component that lets you select group of components and disable/enable with boolean.
