Set Personal Password For Unattended Access From Command Line

I have 100 Raspbery Pi devices with TeamViewer Host on them, at different remote locations across the US, on my Company TeamViewer Account. We forgot to set Personal Password For Unattended Access on a few of them so we are unable to login to them. Although I can push sciprts to those remote machines. How can I setup Personal Password For Unattended Access or something like that using a script? Is there any guidlines to run TeamViewer Setup from Command Line? We are not on the same network as of those Remote Devices so SSH in not an option.
