Remove lifeline from specific device endpoint

I am working on a driver for a device that has 10 endpoints (5 buttons, 5 relays). When a button is clicked the device sends a bunch of events from the device's button endpoint back to the hub and then a relay endpoint also sends a bunch of events back to the hub. Hubitat gets choked up pretty quickly by this. I want to disable the lifeline association of the relays (as an option to reduce chatter back to the hub). How do I do this. Presumably with multiChannelAssociationRemove or multiChannelAssociationSet, but what parameters? Lets say I want to remove the lifeline (group 1) for endpoint 5 back to the hub?
