Configuration in ZCML will be executed at Zope startup and is inherently 
global. Utilities defined in ZCML will be registered with the global 
site manager.

You can try to move the utility registrations to a GenericSetup 
extension profile into a componentregistry.xml file. When you install 
that profile into a specific Plone site, the utilities will be added to 
the local persistent site manager in the Plone site root, thus making 
them local to the instance.

I'm not 100% certain that this works but see no specific reason why it 
shouldn't work. After all these are just normal utilities.
