Can I disable watchdogd process permanently?

I've read this discussion and followed the process described here to disable watchdog.

After rebooting, I'd opened KSysGuard's Process Table and searched for watchdogd and it's still there under kthreadd.

Is this watchdogd the same one I tried to disable in following way?

1) I've set both /proc/sys/kernel/nmi_watchdog and /proc/sys/kernel/watchdog to 0 and rebooted, nmi_watchdog remains 0 BUT watchdog somehow gets set to 1 as before and watchdogd gets listed in process table!

2) I've created a file named blacklist.conf in /etc/modprobe.d/ and added these two lines therein:

    blacklist iTCO_wdt
    blacklist iTCO_vendor_support

since lsmod | grep iTCO returns those two lines, rebooted and I found watchdogd in process table and watchdog gets set to 1 as before!!

3) Instead of those two lines in blacklist.conf file in /etc/modprobe.d/, I've tried with these:

    install iTCO_wdt /bin/false
    install iTCO_vendor_support /bin/false

results are same as (2)

4) I've tried by adding nowatchdog, nmi_watchdog=0 and watchdog=0 in /etc/default/grub like these:

a) GRUB_CMDLINE_LINUX_DEFAULT="audit=0 loglevel=3 quiet nowatchdog"
b) GRUB_CMDLINE_LINUX_DEFAULT="audit=0 loglevel=3 quiet nmi_watchdog=0"
c) GRUB_CMDLINE_LINUX_DEFAULT="audit=0 loglevel=3 quiet nmi_watchdog=0 watchdog=0"

ran grub-mkconfig -o /boot/grub/grub.cfg and reboot

BUT I couldn't get rid of that watchdogd from process table and watchdog turns into 1 as before!

5) I then in addition to the blacklist.conf file in /etc/modprobe.d/ set nmi_watchdog, soft_watchdog and watchdog in /proc/sys/kernel/ to 0 and added this in /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="audit=0 loglevel=3 quiet nowatchdog"

ran grub-mkconfig -o /boot/grub/grub.cfg and reboot

now all of nmi_watchdog, soft_watchdog and watchdog values remain 0 after reboot, no iTCO_wdt and iTCO_vendor_support in lsmod but in KSysGuard's Process Table, I still see the watchdogd process under kthreadd!

How can I get rid of this DOG!
