I can't find it either and will open a case with VMware. The option appears to be hidden in the profile somewehere. You built or updated your host profile from a machine where the option was automatically changed from the default, possibly by adding to a cluster.
On those machines which are not compliant, do the DRS thing as suggested or go to the host's Configuration > Software > Advanced settings > Mem and change VMOverheadGrowthLimit to the maximum of 4294967295.
A check for compliance will now give you an all green.
