A good rule of thumb if you really need the instance of a class is to look for static fields/methods/properties that contain an instance of that class. BNM also allows to make your own update functions.
If you open the dump DLLs inside dnspy right click on the class and click analyse you will see all class that also implement or call that class sometimes there is nothing but sometimes there is then you can just make a pointer from that class to the instant of your class to access everything that's in your class is a bit hard to explain but your get it done
