Accessing viewport configuration via maxscript

Hi everyone,

I'm having a bit of a problem figuring out how to access the safe frame controls via maxscript - specifically, I want to run a script to unlock and set the user safe to some preset values.

Yes, I know how to toggle the safe frame off and on with

displaySafeFrames = true

but that's not what I want to do, I want to modify the various controls in the viewport configure safe frames panel via maxscript.

I'm trying to find INI settings that correspond to these parameters but am not having much luck. These settings are viewport-specific and therefore scene-specific, so I'm not really sure where to begin. Any help or ideas is greatly appreciated!

Thanks so much!
