Turn off notifications if a contact sensor is left 'open'?

Forgive my ignorance, but how do I go about turning off the notifications when Smart Home Monitor arms but a contact sensor has been left ‘open’?

What type of notification are you referring to? Do you mean avoid SHM from getting triggered when a contact sensor is left open?

Apologies - should have been more clearer - those are the ones.

The reason i ask is because im using a google calendar event as a virtual contact sensor and everytime i leave the house while the ‘event’ is still taking place i.e. open, i get push notifications.
