I'd say if it isn't broken and you don't need new features that might be included in a driver then don't fix it.
I always remove the driver updater component.
CCleanerDU.dll
If you're using the free version it will likely prompt you to purchase PRO to update drivers.
See:

Frankly, I would avoid updates from Ccleaner like bubonic plague.
It is supposed to be a cleanup tool (and pretty dubious at that). You start messing with unnecessary driver updates, you ADD crap.
