This really isn't coherent so I'm taking a guess. Hydraulic chuck, you back off
the pressure should come off. Some lathes have two pressure chucking, you clamp
to rough like a mad man and then lighten up on the pressure to do the finish cut
distorted bores that are tri lobed or other distortions.

Let me see if I can clarify. Yes, hydraulic chuck. I was thinking
due to the check valve in the system that holds the chuck closed in
the event of a power failure, you would need to release and reclamp to
have a new setting take effect if you decreasedthe pressure with the
chuck in the clamped position.
My lathe has only one setting, manually made by turning a pressure
adjusting knob. M codes to open/close only.
