RMMZ Locking main class with Visustella class plugin?

[Droxious]

Having a bit of an issue finding what I need on the help page for the class system plugin I'm using, and could really use some help.
I plan on having every actor in my game have a totally unique class that they are locked into, and then have several sub classes that can be swapped on the fly. I'm pretty new to a lot of this and so I may have glanced over the setting but I can't seem to find one that locks the main class only allowing for the sub class to be changed.
