Currently, when the "Select" option is unchecked for an item, it cannot be selected in the viewport, but it can still be selected through the tree view. This is useful for managing complex scenes where certain items don't need frequent selection. While there isn't a built-in feature to temporarily override this restriction directly in the viewport, you can manage selections efficiently by using the tree view to select items. This approach allows you to maintain control over your selections without needing to toggle the "Select" option frequently.
