Is there any way to prevent the preprocessor from calculating the second-order dynamic model derivatives without running stoch_simul with option order=1? I just want Dynare to produce the modefile_dynamic.m with first-order derivatives. I have figured out that I can impose it by using simul(periods=1) in the mod-file, but maybe there is a more efficient way.
Any help / suggestion would be highly appreciated.

I am using the Occbin toolkit which uses dynamic model derivatives produced by the preprocessor and stored in the *_dynamic.m file. Some of model variants do not satisfy the B-K conditions and hence are cannot be run with stoch_simul, which seems to me the only place where imposing order=1 prevents the preprocessor from calculating 2nd order model derivatives. In my case, calculating them is harmful since the model is quite big.
