SharePoint Online Date Calculation

The problem is SharePoint Online treats that as a calculation, and calculations are only refreshed when the item is modified in any way (at least, out of the box). The only way I could find to force the date to recalculate was to create a loop in SharePoint Designer or Flow to overwrite something in an item with its current value until due date = today, which technically changes nothing about the item while still counting as a modification, resulting in a refresh of a date difference calculation. It's an expensive workaround, especially on large lists with lots of due date items, but it's the only non-custom way I know of to manage this.
