I have an Elite Series 2. I disabled clicking down on the sticks and enabled that on the paddles on the underside of the controller. As far as I know, you can do that on the Series 1 Elite controllers as well. You can set the function for clicking on the sticks to 'Unmapped' and they won't function. Again, I haven't tested this on a Series 1 so possibly, it doesn't work the same.
Have you tried remapping the basic controller? Like I said, it would affect all games and apps without being able to select a profile like the Elite controllers have, but it may work still be a good workaround.
Hopefully, we'll allow button remapping at some point in the future. For now, this is the best I can recommend.
