Change gpm cursor effect

Is there a way to change how the cursor displays with [tag:gpm]? In my Debian terminal it shows up as a light grey box that's easy to keep track of, but when I use it within one of my Alpine containers it changes the color of the text its hovering over, which is very easy to lose track of. Specifically: I want the [tag:gpm] cursor to display as the solid grey box. How do I force [tag:gpm] to do this?
