Can we change the configuration like sampling duration at runtime without restarting the app?

Currently, we can provide the sampling duration at the time of building configuration and then we provide that configuration to PyroscopeAgent.start(config) method.

But i didn't find any method/api so that i can change the sampling duration/sampling rate after starting the agent without restarting the app.

Please let me know if we can achieve this behavior already and i have missed it or it is not possible for now with current code.

Thanks.

    PyroscopeAgent.start(
        new Config.Builder()
            .setApplicationName("app-java")
            .setProfilingEvent(EventType.ITIMER)
            .setFormat(Format.JFR)
            //pyroscope is service name
            // pyroscope-test is namespace in which pyroscope service is running and listening for profiling data
            .setServerAddress("http://pyroscope.pyroscope-test.cluster.local:4040")
            // Optionally, if authentication is enabled, specify the API key.
            // .setAuthToken(System.getenv("PYROSCOPE_AUTH_TOKEN"))
            // Optionally, if you'd like to sets allocation threshold to register events, in bytes. '0' registers all events
            // .setProfilingAlloc("0")
            .setSamplingDuration(Duration.ofSeconds(1))
            .build()
    );
