I found the answer.
On the new Samsung Galaxy Tab A with Android 9.0 Pie:
Under the settings menu, under Advanced Features, there is an item called “Smart Pop-Up View”
Selecting that opens up a list of apps that are capable of using “multi-view”, and you can turn or off the home screen/lock screen pop-ups from that app. Wyze is listed, so I turned it off.
The notifications still happen, the sound plays, the temporary notification bar drops down from the top of the screen, and then goes away after a few seconds, and the notification is still in the drop down list. It just got rid of the persistent notification icon that you had to tap to go in and close it.
This is pretty close to the experience on IOS.
