PX4 modules working frequency

Hi community, i have a question about modules working frequency and it is much appreciated if anyone could help me in it, is there any way to change mc_rate_control module working frequency?
I’ve already developed a model predictive controller that needs high computation power so when I’m trying to simulate the drone in gazebo, the simulation wont be real time any more(0.2 real time factor), that’s why I’m thinking to reduce the working frequency, how can i do it?
