How to open OVR settings?

Could you please provide me with a step-by-step guide on how to access and open the OVR settings? I'm not entirely familiar with the process and I'm looking for a clear and concise explanation. I'm particularly interested in knowing what steps I need to take to get to the OVR settings and whether there are any specific requirements or preconditions that I need to fulfill before I can access them. Your guidance would be greatly appreciated.
