You probably have a different version. Do you have adaptive DMC?

In the version I have it is in the Image Sampling rollout called "Adaptive QMC" and the quality settings are in a rollout called "rQMC Sampler".

But in newer versions they started calling it DMC.

And you'll probably have brute force instead of QMC.

If stuff isnt there in your version the only way to get it is with a newer version.

The older versions do have a direct computation GI method though ie: Brute force.

They call it Quasi monte carlo now which is I think the same thing that calculates all the glossy effects like blurry shadows, vray light subdivs, glossy reflection refraction etc..

Reading the chaos group documentation is seriously recommended if you are confused about any of this tech stuff (I don't get half of the GI theory). Its pretty heavy going.
