Searching for bike sensors only after activating the activity

Hello :)

My devices:
Edge 520 + HR + Speed/Cadence sensors
Fenix 6X Pro
When I run the Edge, it searches for sensors and connects to them - that's ok, because I only turn on the Edge when I'm cycling.
I paired Speed/Cadence sensors with Fenix too. And here comes the problem - Fenix is still trying to find these devices (or at least I think so). Is it possible to enable the search for these sensors only when the activity (bike) is running on Fenix?

Or maybe I'm wrong and it's exactly as if I wanted to - it's only when I start the "bike" activity that Fenix starts searching for sensors ?
