After performing a system update and rebooting the device, the Enable NPU option still does not appear in the overlays menu.

Thanks for reporting this.

I checked the current page, and this case is already covered in the Board driver configuration note:

• sudo rsetup -> System -> System Update
• reboot
• then go to Overlays -> Manage overlays -> Enable NPU

Doc reference: https://docs.radxa.com/zero/zero3/app-development/rknn-install

So I’m not opening a docs PR for this one right now.

If Enable NPU is still missing after the exact update + reboot flow above, please reply with:

1. the exact image / release version you are using
2. whether System Update completed successfully
3. a screenshot (or text) of the Overlays -> Manage overlays menu after reboot

With that information we can determine whether this is a remaining docs gap or a product/image issue.
