Wall treatment - RSM turbulence model

I'm modelling a cold chamber with Star CCM+ using RSM turbulence model.
With this turbulence model, Star CCM automatically select the high y+ wall treatment because RSM model is more valid when near wall cells are located in the log law region (high y+ value).
However my question is, what's happening when the y+ value falls below the recommanded minimal value (12).
I've read that in Fluent an hybrid wall treatment is available which switch automatically the resolution depending on the y+ value when y+ is above or below 11.225.
Is Star CCM doing the same even if the high y+ wall treatment is selected ?

We do three types of jobs here:
