    Yes, using an indicator is the right way to go. And it is very easy, you just need to invert the direction of the indicator. Instead of

    f_r > 0 -> i_r = 1

    you would enforce

    i_r = 0 -> f_r <= 0

    This is mathematically equivalent, and it fits to how indicators in Gurobi are defined.
