The Terrain Protocol has a Metals single step Preset, if you wish.
Fungus will depend on what fungus strain is present. There are different strains. In the Morgellons & Lyme Protocol are 4 Presets for Fungus and Mold, although I don't recommend starting with them, as this could create significant other issues. It would be better to just start and go through the whole protocol.
