No. We disable quick grading because graders usually attach feedback/response files. I was referring to the 'grading' page which contains a table listing each student with his/her submission(s). In the Edit column one can 'Prevent submission changes' which seems to be the same as selecting a record and 'With selected' (below the table) choosing 'Lock submissions' > Go.
This lock is different from locking the grades in the gradebook.
