macOS DDM, audio control?

I've installed DDM (Dell Display Manager) which allows me to control basic display functions like contrast and brightness. I also want to control the audio volume from software (today I have to use the monitor's buttons to adjust the device's volume).  Is this feature slated for release?  If so, are there timeframes for when this will be released?

MacBook Air M2, 13.3.1 (a) (22E772610a), Dell U3419W with latest firmware.

Note: I've also installed "MonitorControl" which can adjust the monitor's volume so I know it is possible.
