I am afraid that if it is not, then there is nothing to talkabout.

But the question is interesting. All definitions I know (probability,
possibility, empiric confidence factors etc) are dealing with
uncertainty defined as a set isomorphic to a set real numbers. As such
they ARE quantified. Now, what do you mean? Either you want to move up
to higher cardinals or down to say "uncertainty is damn uncertain". In
either case, it looks not much promissory.

>and that there in only one certain definition of uncertainty...

Is your definition certain? What is "risk"? Why a quantified risk is
certain. Is it? Driving a car, have you some quantified risk of an
accident? Is that certain or uncertain to have an accident if you have
a certain risk of having it? (:-))
