How can I disable the guide screen

I wish to disable the guide screen. I mean the screen which appears eg. 70 meters before a turn point. In Fenix 7 series it could be switched off in the navigation menu. In series 8 the navigation settings have to be done in each activity individually, I vainly searched in an activity but could not find a switch for what is called in series 7 'Guide'.

Please help. Thanx in advance
