There is a pin-out diagram for the disable dongle given. Wire up a new dongle with a simple serial cable and a button on the end. Since the robot is disabled without the dongle, it is most likely a "Open = Disabled" so a regular button would work fine with it.

3.1.7 Competition Port Pinouts
The competition port is used to enable / disable the robot. A “dongle” is provided in the Kit of Parts
for teams to use for this purpose when not in a competition. If teams need to make a replacement
dongle or need additional spare dongles, a team-constructed dongle can be fashioned by
connecting pins 8 and 9 of the competition port to a switch. NOTE: it is essential that the other
pins of the connector be left unconnected, as some of the other pins contain power and/or ground –
So you'll have an in-hand disable button. You release the button, and the robot becomes disabled.
