how to stop microdds-agent from running?

As soon as I install voxl-ros2-foxy, I see topics being published

I didn't even installed voxl-microdds-agent, voxl-mpa-to-ros2
How can I let voxl stop sending these message?
I just want to run the agent myself.
Thanks,

@Kyuhyong-You Take a look at the file /usr/bin/voxl-px4-start. That is the file that starts all of the PX4 drivers, modules, etc. Look for the microdds_client start -t udp -h 127.0.0.1 -p 8888 line and comment that out.
