Does the Norinco 3-9X40 scope with fixed objective lens need parallax adjustment for a 10 meter target with lower magnification if it is zeroed for 30 meters? If yes, then how can it be done?

A fixed objective lens scope has a parallax free distance. Changing magnification does not effect that parallax free distance. Changing that distance requires moving the objective lens in or out in the tube. If you do that yourself, you'll void any warranty and perhaps allow dust and moisture inside. Fogged scopes are useless.
