Yes, FIELDDISPLAY will turn the background completely off, but then you can’t tell where the fields are. Most particularly the ones that are blank at the current time, but are available to be filled out. We have a lot of blank Fields created in our Cover Sheet and Title Block drawings that will later be used to fill in revision dates, etc. throughout the Sheet Set. Once you turn the background off you really can’t tell they even exist in the drawing. So far I haven't found anyway to just control the Field background color.
