How to suppress #Progress from c++ CLI

when runnning a command from c++ CLI, how can you suppress the #Progress: 0 meter?
I can redirect to a file on linux, but I was curious if there a better way to deal with it?

example command,

"N4ITKBiasFieldCorrection MRA.nrrd MRA_BIAS.nrrd

You can call SetQuiet on the plugin watcher to reduce progress output. However, probably redirection to file is simpler - it works on Windows and Mac essentially the same way.
