I was able to enable Silent Mode on my 2015 F-150 Platinum via the Sync screen. You will need the -E* firmware and enable the feature in the Sync asbuilt.
Here are the details:
There is another feature called “Silent mode” that appeared in Sync 3.4 earlier. This incorporates the features of BCM Silent Mode 5. I never could get this to work on my 2015 F-150 Platinum thru Sync, but with the MY18.5 -E* firmware upgrade it appears to be functional. This requires no updates to the BCM.

“enable SMCF - requires 3.4 and MY18.5 -E* firmware”
Here is the feature description:
Silent Mode 5: Unlocking, locking (whether with the key fob, keyless entry, or the keypad), opening any doors, closing any doors, opening the tailgate, closing the tailgate, etc…no exterior lights come on, no interior lights (mostly) come on, and no beeps/horns sound.
Notes to Silent Mode 5:
- When you open a door, the startup logo sequence still plays on the center Sync screen, then it shuts off. The dash screen also cycles on and stays a black screen, then turns off as well.
- The light blue backlighting on the light buttons above the rear doors stay on, all other backlit buttons stay dark.
- If you click a button on the keypad entry, the keypad lights up.
- If you click the bed light button in the bed, those will come on along with the convenience lights on the mirrors.
- The alarm button on the key fob will still flash lights and the horn, if activated.
- Once you turn the ignition on everything will function normally.
