Unable to use Quasi-Newton stabilization in system coupling

For my PhD project, I'm working on FSI models of abdominal aortic aneurysms using Ansys Fluent and Mechanical. Due to the nature of the physics, the added mass effect often causes my models to become unstable. So far, I've been using Ansys 19.2 and I've been experimenting with under-relaxation factors to stabilize my solution. Last week, I read that a new stabilization method, called the Quasi-Newton stabilization, is available in Ansys 20.1. I've installed Ansys 20.1 to try this new stabilization method in the GUI. However, I haven't been able to find the stabilization option. I've included a screenshot of the GUI lay-out. In the data transfer section, I'm able to define the convergence target, under-relaxation and ramping, but I don't see any options for stabilization.

Please let me know if you know how to add the stabilization method in the System Coupling GUI. Thanks in advance!
