Why are usb+ - grayed out? Can they be used?

Hello just wondering why the usb+ - are not used and grayed out, can they be used? Can I use them to connect something else like a screen or another module like it's a USB hub?

They are the same USB signals used for the USB port. As such you can't use them.

You can use them to directly wire a usb cable (if you also connect gnd and 5v) and then not use the usb connector on the board (if say you break it off by being stupid)
