Why would the overlay need to be with the board that had a coating? Buy two boards, cover the parts on one board that are silver, shoot IR. Use second board for visible wavelength photo, combine for a beautiful overlay result.

Why would you assume that they are different boards?

It's not an assumption, it's a suggestion for making an thermal/visible light overlay photo where the IR photo shows only emitted light.
