The BMI interface does not support getting derived variables (min, max, avg, var) nor does it support setting of input parameters. It does support some externally controlled time stepping. Externally set time steps are maximized according to the CFL condition. Negative time steps make the model to skip the absolute value of the time step in time, without executing any model. The external program should provide the updated model state as well.
