I'm able to turn off Home Control in the settings.
Normally, you simply tap your finger on the slider, and it moves to the opposite selection. You might even barely slide your finger to the left or right to make your selection.
I was able to inactivate the "Home Control" by tapping and then sliding my finger left all the way over to the "Home Control" text.
BUT, after exiting and then re-entering Touch ID & Passcode, I can see that the Allow Access When Locked option for "Home Control" is reactivated.
It's not a deal-breaker, of course, but it's pretty annoying.
