It can be handled the same way, but doesn't need to be. Noise must be
handled by filtering, with with a specific inline filter or effective
filtering by means of a control loop. DC will also be handled that way,
but for DC there is always the option of trimming it away with either an
adjustable or an SOT. You can't do that with noise, which makes them
fundamentally different things.
Trimming will only cancel the offset that is present at that instant. When
it drifts (and it will), you will experience offset again. Adjustable
trimming solutions can be viewed as very low bandwidth control loops (with
the person doing the adjustments closing the loop). There is no fundamental
difference.
