Yes, there is a way to disable Plus! temporarily:

Go to your Messenger folder (C:\Program Files\Windows Live\Messenger, might be different depending on your version) and find msimg32.dll, rename it to something else, like msimg32.dll2.
msimg32.dll is a file added by Messenger Plus!, it takes care of loading Plus! whenever Live Messenger starts, renaming or deleting it will stop Plus! from loading.
That way, no part of Messenger Plus! will be loaded when you start Messenger. To enable it again, just rename the file to msimg32.dll again.
