I see two simple possibilities:

        * Keep the original options around at the driver level.
          Allow individual options to be set by modifying the
          original options.

        * Don't add any support for setting options at the driver
          level at all but instead just destroy the driver and
          create a new one with a new, complete set of options
          that has been adjusted as necessary.

Will one of those work?
