Notify When Left Behind turns back on after being turned off

I want to disable Notify When Left Behind for my iPad (which I normally don't carry with me) and some of my AirTags (which are not currently in use). However, it doesn't seem possible to do this and have it "stick".

When I move one of the tracked devices to a new location, Notify When Left Behind re-enables itself. When I look at the setting for the device in the Find My app, I see that NWLB is turned on again, and there is a new entry in the list of "Notify me, except at:" locations. That location is where I was when I disabled NWLB.

It appears that disabling NWLB doesn't really disable it--it only adds an exception to the notification list. When the device is moved to a different location, NWLB turns back on.

(Why is this an issue? Because I live in an RV and travel full-time. So each time we park at a new place, NWLB turns back on for all my devices and I get a barrage of notifications on my Apple Watch and iPhone the first time I drive away from the RV.)

I'm not sure if this is a bug or a feature. If it's a feature, is there really no way to totally disable NWLB for a given device, short of removing the item from Find My completely (and thereby losing the other Find My functions)?
