If you can find out the name of the driver(s), then removing them is the easiest way.
The name will be in the script somewhere, I've had a look but nothing obvious.
Maybe removing the control centre gets rid of the drivers as well, reboot, reinstall and see if it thinks you have any drivers already installed.
A fresh flash with no settings/plugins restore would do it, but more work to get going, and then there's still the shell script to run.
