Same problem, I have to essentially disable it to make a Macbook-with-Touchbar usable.
Go to its settings, disable per-app configuration so it always stays the same, then, from whichever part of it you accidentally brush most often (for me it's the right half or so) replace everything with a "spacer" element, so it's blank.
You can still use the function toggle to see your F-keys if you need them.
I also have to disable the force-sensitive functionality on the touchpad or I can't reliably perform drag-n-drop operations. Took me way too long to figure out what was making that happen.
IOW I have to disable all the fancy new hardware "features" on modern MBPs to make them usable. And god, is #DongleLife ever even worse than I expected it to be.
