FVGs are essentially the same thing as single prints. I have been able to print them by using just the built-in TPO study in MotiveWave (with everything except single prints hidden)
The result is not perfect and you will have to play around with the settings, but maybe this will be useful to some people.
Setting the TPO sub interval to the chart timeframe and the TPO timeframe to sub interval multiplied by 6 seems to work quite well, but I haven't tested it that much. Tick interval will depend on the asset and timeframe.
