Yep,
As has been stated, Jeep has its head up you know where when it comes to some of it's owners manuals and, flat towing. They're building and selling one of the hottest selling vehicles on the planet and for some reason, they can't seem to figure our, HOW TO MAKE AN OWNERS MANUAL! I really cannot speak for preparations for towing a '17 Wrangler but, on our '15, there is absolutely ZERO need to disconnect the battery when towing. We never have and never will.
At the end of a days towing, I want to get in, start it up, un-hook the tow bar/cables and pig tail and, DRIVE AWAY. I sure as heck don't want to be bothered with hooking up disconnected battery cables or, even a switch for that matter. I suspect that, the '17 version is the same but, I don't own one so, I would be only guessing which, doesn't help you.
