Root Domain - Enterprise Admin Group

 Hi Everyone,

Is there a way to completely remove Enterprise admin group/Root-Administrator right from Child  domain?  (i.e. removing only Enterprise admin group from child domain-administrators group is still not enough as member of Enterprise admin group still hold certain permission to access resource on child domain, e.g. add/remove child domain users)

Alternatively, is the any article saying we can't do that from Microsoft?

Thanks.
