Install WPMU Dashboard...

I have many plugins of WPMUdev installed, but I see in my admin panel the message:

"Easily get updates, support, and one-click WPMU DEV plugin/theme installations right from in your dashboard - install the free WPMU DEV Dashboard plugin. (find out more)"

I don't want to install the WPMU Dashboard, I just wanna remove this message.

How can I remove this definitively for ALL plugins fast and easy?!?
