The high heart rate alerts on Fitbits only occur when the devices detects a high HR and while you’ve been inactive for about 5 minutes or more.
However, when you are in exercise mode, you DO get alerts when you go in and out of zones. In your case, when you get the alert that you’ve gone into “cardio” or ‘peak’ zones, you may want to back off for a bit. Check out pages 42-43 of the manual.
Hope that helps.
