On the Debian stretch images for BBB is there an easy way to force the EDID to update and/or the display to re-initialize such as if you change the connected display (while the BBB is still running)?

I have noticed that I can switch to a different monitor on the HDMI, but /sys/devices/platform/ocp/4830e000.lcdc/drm/card0/card0-HDMI-A-1/edid will continue to show the information for the display that was connected at bootup. (old EDID)
