See Libre Computer CC Boards GPIO Pinmux Compatibility Matrix
If you are doing custom wires to remap to the proper pins, all boards are supported.
You have to enable the PCM pinmux so that PCM is routed to those pins. Then you have to configure alsamixer to output on the right interface using the right audio format.
If you don’t know how, you can provide the base device tree from https://boot.libre.computer/ci/BOARD.dts and then ask Grok to make an overlay based on the specific pins you want to use and the pinmux on those pins.
