Musescore 4 Mixer - turning instrument chords on and off

In Musescore 3, we had the ability to turn off playback of instrument chords by turning off the harmony function for the instrument in the mixer. That ability seems to have been removed or moved in Musescore 4. I only see the ability to turn chord playback on and off for the score as a whole, not individual instruments. When chords are indicated in instrument parts, for jazz improvisation for example, it plays the actual chord rather than the underlying concert chord, creating a chaos of sound. The only way to playback the score with chords without this discordance is with the score in concert mode.

Please steer me in the right direction! How do I turn off playback for these instrument chords?
