This actually should be done other way around, i.e. enabling ACPI WDAT table will get you watchdog and this is *highly* recommended way.
If I understand correctly you are suggesting to try the wdat_wdt driver instead?
Yes. That driver should be in use assuming properly crafted firmware.
Discussion about iTCO_wdt problem with Intel NUC is here but no solution so far:

I have the latest available firmware for this NUC but there is no such table and loading wdat_wdt module does not find anything.
