No, that is not possible with Dynare. The particle filter currently is still experimental and does not yet support third order. Note that shock decompositions (in the sense of contributions of shocks to particular variables) at higher order are non-trivial due to non-linearity. There is no agreed upon standard way of doing this. If you only want to extract shocks, a particle smoother could work.
You could aslo try to estimate your model using GMM or SMM. An SMM example is contained in our replication files for Born/Pfeifer (2014): "Risk Matters: A comment" on my homepage.
