My understanding is a manual device add approach, while possible, removes the benefits of orch (creating "unmanaged" devices) and should be avoided. But would it even be possible for orch to be fed a yaml with the NVMes operating as both a data and db device?

Check if the NVMe devices support multiple namespaces: https://narasimhan-v.github.io/2020/06/12/Managing-NVMe-Namespaces.html This way the kernel sees two block devices for each NVMe and the orchestrator is able to provision an OSD on one and the RocksDBs for the hybrid OSDs on the other.
