Well I can't on a rental car, or while traveling. Oh well, it was worth
asking. But if Toyota has anything like it, I do have the ability to
set those hidden settings.

After a bunch of work, I got it to work on my car at home, but it's a
2005 and it had very few settings, none of which I wanted to change.
Mostly things about combustion iirc that I'd be afraid to change. The
same software applies maybe to 2019 and beyond. OTOH, Toyota has
stopped making even moderate sized convertibles, which is part of why I
got a 2005 and not newer. Next car might be a Mazda Miata or Chrysler
300.
