Markov_switching command questions

Dynare provides a markov_switching command which, in the documentation description, we can use to define a Markov chain with the following optional parameters:

markov_switching(chain=2, number_of_regimes=3, duration=[0.5, 2.5, 2.5], 
parameter=[alpha, rho], number_of_lags=2, restrictions=[[1,3,0],[3,3,1]]);

I would like to know whether I can define specific values for the ‘parameters’ here under each regime.

That is not feasible. The markov_switching-command is only for VAR models and the parameter values are estimated.
