Maybe Helmut can investigate. I am not entirely sure about that but the linux-based system Qnap puts on this device also just disables the watchdog in one of their init scripts so at least it isn't enabled by the kernel or userspace software. After doing a soft reboot, it will also be enabled again, so either the boot loader on the device (uboot I believe) enables it or (most likely) it is programmed to be enabled by default.
Qnap rather seems to rely on the other (second) watchdog which is also present on the device, seems to use the orion_wdt module compiled into their kernel and is fed by a userspace daemon called "qwatchdogd" which uses the regular /dev/watchdog device.
