Remove password protection from command line

Hi there everyone
I recently deployed Parallels Desktop 12 to several MacBooks along with a win7 vm. The autodeploy package contained a deploy.cfg that configured password protection on making changes to Parallels

the prlsrvctl command allows me to make several changes after the fact, but not if password protection is enabled

For example, when I try to run the following:
prlsrvctl user set --def-vm-home /Users/Shared/Parallels
I get the following message:
Unable to perform the operation. The operation is password-protected.

This is obviously the way it is supposed to be, but my question is can i use a command to turn this protection off? I tried
prlsrvctl set --require-custom-pwd edit-preferencesff, but i get the same message (because it too is password protected)

So, is there a way via the command to change? I know how to do it via the gui, but don't want to do this for the entire lab

Thanks
