Because of https://issues.jboss.org/browse/TEIID-4957 a customer would need to be able to set the Connection Type on a VDB in the Designer before deploying it. There currently is not a way to do that. You cannot use the User Properties because it writes to the vdb.xml as <property name="connection-type" value="NONE"/> and it needs to be <connection-type>NONE</connection-type>
