No, driving characteristics such as Real Drive are controlled by the actual sound file that is loaded on to the decoder. The CV's have no control over this. personally I'm not too fond of the Zimo decoders. The braking and coasting features are very good but the way the engine sounds react to throttle changes leaves a lot to be desired IMHO.
However, ESU recently realeased a new set of soundfiles that have similar features under the name "Full Throttle". These include a working brake, a "Coast" function which brings the engine sound down to idle while you control the speed independently with the throttle as well as "Drive Hold" which locks the speed of the loco while you adjust the engine sound with the throttle. Sounds complicated but is simple in practice.
I've programmed one of my own locos at home with one of these files and it works great. You can achieve very realistic running with it. I was planning to post a video of it when I get the chance.
Here's a video from ESU's YouTube channel. It's a bit long winded but you can get the idea....
