Disable notification/permission to pair in NRF52


In-app when you scan for device and after it is found you press the connect and then the notification/permission to pair pops out. Our app developers are saying that we must disable this notification in our firmware, but I can't find any similar settings in nRF SDK. If I connect to the device from nRF connect I don't see any notification/permission to pair. 

Can we disable notification/permission to pair in firmware or not? 

Thanks for help
