Instead of making the user type attendance unmark 1 l/1, we used the prefix m/value so that the command is more flexible and combined with our input history feature will help typists type attendance commands faster.
TLDR attendance mark 1 l/1 m/0 is the feature you are looking for.
There is no feature which will allow me to unmark attendance of a student for a particular lesson. I can only delete the entire attendance list.
