Hi LaurelS.
Thank you for posting in this community and I am sorry for this inconvenience caused to you.
According to my research, I am sorry that I don’t find any out of box ways to do this. So, I am afraid there is not an option to programatically change the data labels in a Modern Chart.
I understand the inconvenience caused to you. So, to address your concerns, I would suggest you send feedback via the Feedback ·Community (microsoft.com) . Since it is the quickest route to get your comments to the related programming developers’ears. They read customer feedback daily.
Thank you for your time and understanding.
Best Regards,
May
