No, the options overriding follow the simple principle: anything you can
supply later should override anything you supplied before. In this case,
command line options override the annotations. In this sense, command
line options provide the final authority on the benchmark execution mode.

Or, you may use Java API to drive your benchmarks if you need something
not in line with the default JMH behavior.
