Disable Zone Alarm in workouts

Hey garmin folks,

i have a new coach and he is using todaysplan. The workouts are perfectly synched to my epix2 and the training goals including heartrate or speed. If I run too slow or fast in a pace based workout, the epix is getting on my nervs with an alarm every 20 sec that the speed is too slow or high. 

I would like to get rid of the zone alarm/notifications and need help to find that option.

Thanks in advance!
