11g services do replace the instance_groups/parallel_instance_group parameters. You define which nodes the service runs on, and which instances it includes.

So yes, you can define a 1 node, 1 instance service to limit PX to that node.

For example:
srvctl add service -d <db name> -s <service name> -r <instance list>
