Welcome to the Forum @jhanks and thank you for reaching out!
As it stands, there isn’t a setting option to change the way due date is displayed. There is an existing thread in the #productfeedback category: Add three-character day of week to date tooltips at least, and some date references too - #3 by kyo. If you haven’t yet, I would suggest you to upvote it!
Please let me know if there is anything else I can help you with! Have a nice day!
