You might add a new folder to the subsystem deployment-scanner
<deployment-scanner name="MyDS" path="deployments-ds" relative-to="jboss.server.base.dir" scan-interval="5000" auto-deploy-zipped=="false" auto-deploy-exploded="false"/>
also yo can set auto-deploy-xml (but this is true by default).
I'm not sure whether this avoid all possibilities but you might also use that folder only for your *-ds.xml.
