Question about how to enable watchdog timer on blkde3815tykh0e

I recently bought blkde3815tykh0e.

I thought the NUC have a feature of watchdog timer.

These document below shows it.

I've already installed latest visual bios(version 0046) to NUC.

But I couldn't find settings of watchdog timer on bios.

It's answered that Watchdog can be enable or disable under the perfomance tab.

Is there how to enable watchdog instead?

And I want to use watchdog timer on Windows 8 or 10.

But there aren't documents and drivers about watchdog timer for windows.

I only could find the document below.

But It's for linux. Furthermore I don't know the document supports this NUC.

Please tell me how to use watchdog timer on this NUC.
