3+ output-DAC support

For a project, we are working on a system that needs to drive 3 or 4 independent audio-exciters. We have been trying to scour through all options that we can find, but haven’t found an ELK-supported DAC that has 3 or more output channels.

Is there a supported way, using ELK OS to chain two DACs together, or is there a known-supported DAC that does allow for this?
