When I create a launch file for a ComposableNodeContainer, a launchrosxxx node gets created. This can be seen when running the launch from this tutorial.

Is there a way for this launchrosxxx node to not get generated? Why is it generated? If I create a launch file with standalone nodes i.e. not composable nodes, the launchrosxxx node is not generated.

If there is no way to avoid creation of this launchrosxxx node, then is there a way to access this node, specifically the ability to set it's log level. The reason I need to do that is there are some discovery warnings in my system that I want to suppress.
