Option to disable hover border for cards on dashboards

I believe that a recent'ish update has added a light blue border when users hover over cards on a dashboard. Having the option to disable this behavior would be a great improvement. For some cards, particularly some DDX bricks, the border breaks the sense that the card is an element on the page.

I have an album showing the difference here:
