The Lockheed L1011 TriStar-500 had ACS, "active control system," that would partially deploy "speed brakes," also known as "spoilers," to dampen wing flutter during turbulence. The TriStar also used DLC, "direct lift control," a partial, variable, deployment of spoilers during approach in the landing configuration to help maintain continuous body angle.
The use of manual speed brakes during turbulence is not an operational procedure. The autopilot by itself will handle light to moderate turbulence without disconnecting. In severe turbulence most autopilots have a CWS, "control wheel steering," mode, or equivalent, that would assist the pilot to manually fly the airplane by augmenting manual control inputs.
