To have watchdog quiet during kernel boot it is necessary to change gpio wdt trigger direction.
Sorry, this is not a good explanation. You force a GPIO to drop a feture, instead of disabling the feature itself. And maybe some other people want to have this feature enabled.
Which is the timeout for the watchdog ? Why is it hitting too soon ?
Fix should be not done simply removing the effect, but checking the cause.

I do not think this a right way to disable a watchdog.
