KeyTips now available in Office for Mac

Is there a way to either disable this feature entirely, or to re-assign the trigger function to another key? I can't find any settings (I am on the insider/beta channel).

I understand the value of the new feature, but the Option key is such a commonly used modifier key on the mac – e.g. in conjunction with other keys for diacritics, accents, non-breaking spaces, en/em dashes – that any slight typing inaccuracy where you haven't pressed both keys exactly together takes you out of the typing flow and into navigating the ribbon.

At best, there's the irritation of losing your place and having to go back and retype, at worst, you have accidentally activated an unwanted function, and need to undo your way back to where you were. That quickly gets frustrating when it happens repeatedly.
