Disabling Dolby Atmos MAT2.0 with an Apple TV 4k 3rd gen 128gb OS26

I have an Apple TV 4k 3rd gen 128gb model connected to a downstream device that is compatible with all surround sound formats except object-based ones like DTS:X, Dolby Atmos and Dolby Atmos MAT2.0 .

However, I would still like to have the highest possible audio output from the Apple TV 4k and not have to downgrade to the lossy Dolby 5.1 or stereo options when playing back content with Atmos audio (only that is affected since all other non-object-based audio is output without any problems since the problem arises from the MAT2.0 encoding for Atmos content which my downstream device is not able to decode).

Please let me know if I missed a setting that can resolve my problem and otherwise please either consider adding the option or including me in the closed beta for the Apple TV OS26 since I heared that an option for audio-passtrough is in the works.

Many thanks already in advance!
