Who advised you to harden it this way, if I may ask? MS wouldn't.

It is listed this way in the NISP Manual
Ok, then ask them how to remove it AND let them confirm it's not a typing error of some kind. Because windows won't let you, it needs this config.
I am not sure if there is a way to set this, there used to be the old tool ntrights.exe but this very privilege you mention, cannot be granted/revoked with that tool (while others can).
