How can I disable TrueHarmony on my Nitro 5 AN515-54-54W2?

Defiect

I have a very good pair of headphones that I'd like to use with my Nitro 5, but TrueHarmony is negatively coloring the sound, so I'd like to disable it.

I see online that there should be a TrueHarmony tab in my Speaker properties settings in Sound settings, but that tab is absent. I only see General, Custom, Levels, Advanced, and Spatial Sound. There are no options for TrueHarmony in there. Furthermore, the NitroSense software only has options for changing the sound profile of TrueHarmony, no options for disabling it.

I believe I have found it, the Waves MaxxAudio software that comes preinstalled had a toggle button on it, clicking that seems to have disabled the sound coloring.
