Easily disabled with ForScan. Then, you wouldn't have to remember the button every time. The first line will disable A.S.S., and is all you really need. The other two lines just take it out of the dash menu and remove the grayed out icon on the dash telling you A.S.S. is disabled.

The program is (for now) free because it is a beta version. You will have to buy an OBDII device to connect the truck to your laptop computer to run ForScan. You will have to request a license from the programmers, but it, too, is free. All of this is specified in the link in post #1.

You shouldn't be able to turn the wheel much, if at all, while the engine is stopped.
Turning the wheel 90+ degrees before A/S/S shuts it down should prevent shutdown. Turning the wheel after shutdown (if that's even possible) does not cause the engine to restart.
This is all explained quite well in the manual.

I see now, lynux3. My experience with this is with my '16 and the 2.7 EB. Maybe other years or engine combinations are different, although from others' comments in other threads, I was under the definite impression that they all worked the same way. Interesting.
In my truck, with the engine off due to Auto S/S engaging, the power steering is off (but not locked), just as it would be with the ignition off for any other reason; so turning the wheel to restart the engine is all but impossible.
Logically, since the power steering is electric, it should, or at least could, still work without the engine running, as yours appears to do. According to the document tmcolegr posted, it could be that this implementation started with the 2018's. Your post is the first I've seen that indicates that power steering in some trucks really does work this way. My apologies for the confusion.
What year is your truck, and what are the build details?

So, you roll up to a light and the steering wheel is straight. Auto/Stop Start kills the engine. With just a slight tug on the wheel the truck restarts. I do not have the issue the OP has. He can literally turn the wheel as hard as possible and the truck will not restart.

My brother's 2018 F-150 Lariat
1.) Auto Stop-Start engaged (engine off)
2.) Steering wheel straight.
3.) Minimal steering wheel input restarts motor (engine on).
My truck behaves differently, however. Here is the video again of my truck showing the exact following:
My 2018 F-150 Platinum
1.) Auto Stop-Start engaged (engine off).
2.) Steering wheel straight.
3.) Excessive or minimal steering wheel input does not restart motor, engine stays off.

My 2015 won't let me turn the wheel with the engine off because the power steering is powered down. I've given it a bit of force but never really tried too hard to turn the wheel for fear of breaking something. The engine will not restart on my 15 if I try to turn the wheel.
The power steering is instantly back as soon as the engine restarts though, so I can lift my foot slightly to start the engine and get power steering back without the truck moving at all. And I've found that a half turn from center won't prevent the start-stop, it's about 3/4-1 full turn that will keep the engine running.
Sounds like newer models keep the power steering running with the engine off, but I wonder how much of a drain that is on the battery and how that affects the length of time that the engine will remain off. The system is designed to restart if the battery level begins to drop too much (among other reasons).
