It'll just be another USB port, nothing special. You can get the same effect by plugging a hub into one of the existing ports.

It's not exactly a way to "disable" the header; if the pulldown resistors are missing, it's because they're unnecessary when the USB connector is missing.

That'll make more of a difference than the USB port. If the necessary components behind the VGA header are present, you'll be able to attach a monitor and a USB keyboard to change BIOS settings.

If you can use it to get into the BIOS settings, there's no need to solder a VGA header onto the board.
