Remove Audio from AccuLips Viseme Animation

I am using AccuLips and I want to remove the audio AFTER the viseme animation is created so it does not get embedded when I export the FBX. I no longer need the audio but if I try to delete the audio portion of the track, it removes the visemes as well. Is there any way around this?

I thought FBX files don’t actually include audio, at least not standard.

Same here, I’ve never heard of FBX including audio data, either.
