We are using Moodle 3.4, and we have enrolled a number of users into a course, however their roles were not set.
Can we just edit the user roles (to add Student role) by csv? I went through the below documentation but unable to find something that suits my situation.

Otherwise, can I just re-upload the list of students again, this time with student role defined, would it disturb the database in any way?
