Disable "On course" alert?

Hi,

Anyone know how to disable the "on course" navigation alert in the Fenix 6? There's a setting for the "off course" alert but I can't see one for the "on course" alert and it's annoying and a waste of battery life on long hikes.

Alternatively, does anyone know how to expand the distance tolerance for what is considered on course? If I could expand this to, say, 1000 meters then the "on course" alert wouldn't need to trigger, except maybe at the start.

Thanks,

Michael
