Can smart charge be disabled?

The problem is, FEW people know about the BMS including dealership technicians. I think this is because it's such a ridiculous system that serves absolutely no true benefit whatsoever that nobody would ever even assume that something like that would be a "feature" on a truck.
There is no telling how many dealership service visits there have been related to this system because people (and some dealers) don't even realize that the truck is designed to do this.

"The load shed operation, go read it again, and again and again until you understand how it works. It's reducing the load on the entire electrical system saving otherwise lost voltage the alternator would have to make up for."
I disagree, it is NOT reducing load, it is reducing the charge to the battery.
Its that simple.
These trucks are running around with 80% charge to the battery to save .0000000000000000000001 MPG.
""They even told us straight up that a vehicle would roll off the line with a known defective part because it's cheaper to pay us in the field to fix it than stop the assembly line. How's that for a slap in the face? """
Which is the reason I wish I had never sold my old 1995 F150. My 2013 is junk.

My 2013 rocks too. But that doesn't mean there isn't some really stupid engineering in these trucks that does absolutely nothing beneficial.
With the BMS system disconnected, my truck starts just as quickly as it did before. So there's no difference that the starter motor can see. And I'm not worried about the alternator because it's there for the purpose of charging the battery. I'd rather have full battery capacity. Fuel economy? We've already talked about that. Zero benefit to this system. But lots of headaches with it.
Just like the vacuum hubs...just another failure point that the competition doesn't have and they all get the same highway MPGs that we do.
I love my truck. That doesn't mean it's perfect.

I didn't see any mention of fuel savings in the principles of operation, the main thing I saw is that the alternator is turned off for faster cranking, which in turn by itself helps pro long battery and starter life, what's a new battery and starter cost these days? I know a battery is easily $100, starter? I'm really not in the mood to dig up prices, go search your self if you care to.
The load shed operation, go read it again, and again and again until you understand how it works. It's reducing the load on the entire electrical system saving otherwise lost voltage the alternator would have to make up for.
You don't understand it so you don't like it, I get that but for the majority of the truck driving world it's a non issue or shall I say your more intune to first world problems.
Batteries last longer, alternator lasts longer, starters last longer unless you happen to have one of those new trucks with start/stop technology, now that's where you start seeing more benefit but I digress.
Don't get me started on dealers and the tech's that no longer exist at most of them, I am very well familiar with the situation and it's sad but it's the manufacturers fault for screwing tech's with the unfair service labor time standards on warranty work.
They even told us straight up that a vehicle would roll off the line with a known defective part because it's cheaper to pay us in the field to fix it than stop the assembly line. How's that for a slap in the face?
Nearly every tech where I work now was a dealer tech from one brand or another, 3 of us from Ford, 4-6 from some type of GM dealer, 2 Dodge tech's, 2 Toyota, and 2 Lexus techs.
That's where we went, where we would get paid fairly!! Best I can tell you is if you find a dealer that has a seasoned tech, hold on with a death grip!

No hard stops or towing.
New technology sucks !
I want my 1995 F150 back!
Smart charge sucks !
