How to disable audio notifications when following a course

Hello,

In the Garmin Connect app I disabled all audio notifications. Still, when I'm walking a course with intermediate waypoints, I get a voice notification (female, English) when I approach a waypoint. 
I want to disable this, how to do?

I use the Fenix Pro Solar Sapphire and the garmin apps (Explore, Connect, Connect IQ) on an android Samsung Galaxy S23.

Thank you in advance.
