Define Redshift log level when submitting houdini job



I’m sending houdini-redshift job to deadline but redshift don’t output any progression log and deadline cannot display the %% of each frame.
redshift staff say that the log level must be set to ‘Debug’ in order to get the progression of the currently rendered frame.
where and how can I setup deadline so it execute this line when launching hython.exe ?

hou.hscript("Redshift_setLogLevel -L 5");

thanks you very much !
