Checkbox for Enabling Unconnected Socket

When creating a node group in the compositor (Blender 4.4.1), any unconnected sockets are displayed in gray, which is a useful feature. However, it remains grayed out when I want to control a setting with a socket using drivers.

I propose adding a checkbox in the socket settings that enables it without needing to connect to another socket.

Currently, the only workaround I’ve found is to connect it to an empty File Output node.
