Install full client with no "host" features

Is there a way to install the TeamViewer full client to allow remote control of other devices, WITHOUT the "host" part ?   

As in, we want to allow our help desk to do remote support, but we want to completly prohibit their workstations from being remote-controled.

-> Company has a proxy, so we can not use the "TeamViewer_Assignment" tool to automatically file the computer and apply a security (or so we were told by TV support...).

-> We can install the client and then use the Management Console to apply a security strategy to the device, but this leads to more human manipulations that we would  wish for for an installation.

Is there a way to de-activate the host from a more-automated way ?   Like a registry key that would completly block it ?
