oops. this is not even a SIM card. can this be disabled? will the devices override user preference and still continue to communicate .

If you have a device that tries to use sidewalk, you could put tinfoil around the device or desauter the bluetooth chip/900mhz radio (and hope the device works without them in there), but that's really it if these devices come out without a setting to disable sidewalk.

If you have an Echo/sidewalk-capable device already, you can opt-out of allowing other devices to use your sidewalk in the Ring or Amazon app https://support.ring.com/hc/en-us/articles/360032524592-Opti....
