Once a product is delivered with Dolby Atmos recordings to DSPs, it is not possible to take down the Dolby Atmos audio and keep the stereo audio only. The product needs to be taken down and created again with a different barcode and containing only the stereo files.
Given that Dolby Atmos recordings have their own ISRCs, some DSPs - for instance, Apple Music - consider the removal of Dolby Atmos recordings a tracklist change, which is not allowed.
Note that it if you are trying to update/ replace the Dolby Atmos audio, that is possible after delivery, similar to updating the stereo audio files.
