How do I turn off OVR service?

Excuse me, I'm having a bit of trouble figuring out how to disable the OVR service on my device. Could you please guide me through the process step by step? I'm not very tech-savvy and would appreciate it if you could keep the instructions as simple as possible. I've tried looking for the option in my settings but haven't been able to locate it. Could you tell me where exactly I should be looking and what specific actions I need to take to turn off the OVR service? Thank you in advance for your help.
