There is no mechanical lever or disconnect switch like there is in some aircraft. However, there is an Elevator Control Column Override mechanism. When enough force is applied it will separate the control columns in the event of a column jam. If a elevator jam occurs there isn’t much to do about that.
However, since the Max spoilers were changed to fly by wire, there is the elevator jam landing assist, which will be switched on as part of the QRH. This will “float” the spoilers part way up and increase or decrease deflection based on the FORCE Applied to the column. It works the same as the DLC described earlier.
And trim is available in the above circumstances.
What a mess they have put themselves in.
