For what it's worth, Microchip does have a KnowledgeBase article about this very topic: https://microchipsupport.force.com/s/article/KB100496

To paraphrase here, the basic module that DigiKey sells does not have support for aptX or AAC.
To get the device(s) that do have support, you need to order a different part number:

RN52-I is the SBC version (what we are using)
RN52APT-I is the aptX version
RN52AAC-I is the AAC version
RN52ATC-I has both aptX and AAC.

From what I can tell, this is the only place these different versions are mentioned on Microchip's site, and only website has them listed, but with zero stock and a 13wk lead time. That is AVNET in case anyone is curious enough to try.

I believe this part would drop in if it could ever be found, and it would just require a small tweak to the RN52_SET_EXTENDED_FEATURES command, changing the 4 to a C to enable the aptX/AAC bit.

Would be a nice upgrade, but I don't see it happening, realistically.
