It has but I cannot remember anybody used the manual mode ever.
Four descent modes for Soyuz are:
(1) Automated controlled descent (i.e., computer-controlled entry);
(2) Manual controlled descent;
(3) Ballistic descent;
(4) Reserve ballistic descent.
Of course, ballistic entry is a controlled mode as well, just the
laws of control are different. Not sure what is the fourth mode.
