If you want to do that, I suppose you'll have to attach the bind not to the 
whole ScrolledText, but for its 'text' component, like in:
myScrolledText.component('text').bind('<Key>', lambda event: 'break')

But...

Definetely, yes. Just change the state of the same component to DISABLED, 
as in:
myScrolledText.component('text').configure(state=DISABLED)
(this works if you did a "from Tkinter import *"; if you did "import 
Tkinter", replace DISABLED by Tkinter.DISABLED).

And please note that the DISABLED state is set for you too. That means that 
if you have to change the text in the widget, you'll have to set back its 
state to NORMAL first, change the text and then set the state to DISABLED 
again.
