Configure LCD to be flipped horizontally and used over HDMI?

Hi, I hope this is the right place for this question. I've got the "5inch HDMI Display-B" 800x480 USB Capacitive Touch Rev 1.0 LCD display that is commonly used with raspberry pi. In my case, I want to use it via HDMI andI need the display to be flipped horizontally so I can use it with a teleprompter.
The problem is that the OSD does not support horizontal flip. I also have a 7" model which appears to use the same or similar firmware, and it does have the option to flip horizontal, which makes me think it should be possible to get this smaller display to flip horizontal.
I've found the LCD-show "driver" which is used to configure the display when booting with a raspberry pi, and I'm wondering if this LCD-show drive actually changes the configuration in the NVRAM of the LCD board, so that I could use LCD-show to flip the display horizontal, then unplug it and use it as a plain HDMI display, but have the image appear flipped.
Does anyone know if this is possible?
