You can zero out a row of the body's inverse inertia tensor to lock rotation around a body's local axes. There is no equivalent body-intrinsic position lock; you can do similar things with constraints like the LinearAxisServo or, more approximately, just by setting the appropriate component of the position and velocity to 0 every frame.
