Ability to remove "unmanage" from "maintenance" tab

Hi,

I am wondering if there is a way to remove the "unmanage nodes" and only use the 'mute nodes" from the maintenance tab in SAM 6.4, or can we do any custom script to add in just the ability to "mute nodes"?

Also, when the account is set with the permission to "node management rights", can we disable the ability to "unmanage nodes".

Reason is, we don't want users to accidentally set the nodes to 'unmanage', as it will stop collecting data.

Thank you in advance,

Tim
