While I have never used it, I think you can add in a line using: optimize_init_constraints(S,Cp) as described in the mata manual (page 658). Here, Cp is a matrix with rows=number of constraints, and columns=parameters+1. The +1 is for the constant value at the end of each constraint. As your constraint is b1=0 with two parameters, I think Cp=(1,0,0) should do it.
