the CVT dipstick is locked for a reason, the reason being that if the owner left the dipstick not full inserted dust and dirt would enter the system and the system would lock up, also the CVT pressure is high enough that with out the lock the dipstick would be pushed out.
The way to check the fluid is by computer and the readout will tell you how much fluid life is left. CTV fluid is not need to be change before 60k miles and most of the time even then you still have between 40-60 percent fuild life left.
