T470 Auto Wireless Disconnection option greyed out

Just picked up two T470's and two T570's.  I was able to enable the Auto Wireless Disconnection on both of the T570's however even with a BIOS update I'm still not able to enable it on either of the T470's.  It's greyed out and skips over it in the menu even though I can see it.

Ideas?

Same here on a T470 with N1QET57W (1.32) BIOS

Wireless Auto Disconnection is set to Disabled but greyed out and can't be selected to change it.

We're having the board replaced on ours. Seems rather drastic.

Let me know if that fixes it. I agree it seems very drastic. I hadn't tried yet, but wondered if docking it would enable that option even if temporarily.

The setting isn't unlocked by attaching USB 3.0 Ultra Dock.

Just tried traditional (non-USB) Ultra Dock and no luck.

I guess that's good and bad. At least you know. I've opened a case with Lenovo as well.

We unboxed another of our new T470s and it's the same.

Was just notified that a part ordered was unavailable. I'm wondering if they're going to try replacing the motherboard on mine as well.
Here's the status:
