The audio output from the ATEM is always stereo (2-channel L/R). This applies to the stream output and HDMI program output.
You do have some control over the handling of the audio inputs into the switcher. In the Audio tab of the settings (gear icon) in the ATEM software, you can control whether each audio input is configured as a stereo pair or two separate mono channels. So if you wanted to achieve something like a mono audio mix, you'd just need to make sure that the input signals are treated as mono channels and panned to the center, so that way in the L/R stereo output, both audio channels are identical.
