How to disable automatic new sensor detection

Hello, my wife edge 130 tries to detect all new sensors when powered on !
Every time edge 130 is powered up, it asks to pair all sensor nearby it founds. Pretty annoying for group ride !
Edge 130 has already sensors of her bike paired.
My edge 820 does't behave like that. Is there a way to desactivate automatical new sensor detection ?
It's not conveniant for group ride to discard all sensors of other bikes ...
