How to change the Default 'Due date' for course assignment

Content (please ensure you mask any confidential information):

Hi,

when a course is assigned the learner views in the 'Current Learning' this course, with a due date which is by default, one month after the enrollment to the course (see the attached screenshot).

This due date is not set by the Learning Admin when he/she creates the course or assigns it (therefore it should be a default setting).

How can we update the default setting in order to set a different due date (for instance 3 months after the enrollment to the course).
