How do I disable/remove activities app?

When I take my dogs for a hike (generally in terrain with limited or no cell connectivity), frequently my newer SE-LTE watch (with whatever the latest iOS update might be), will start buzzing me to tell me I'm out for a walk, and wanting to record, or maybe already is "recording" my activity; I have seen both come up. "Go away; quit bugging me :-P"

It is a PITA, especially in winter/gloves, to have to stop and poke at the watch until I find the spot to turn this off. I thought I had it disabled, but one of the recent updates must have turned it back on. I don't use the Activities app, and would like to simply get rid of it, since it refuses to shut up.

Any thoughts?
