No luck required. It’s mentioned in your manual that you need to use the Chord ASIO driver to get DSD512 to it.
So for DSD512 it’s limited to Win10.
See the bottom line here, taken from the manual.
Do you have any Win10 PC in the house? You can use your NUC running ROCK for your Roon Core and a separate PC running Win10 with Roon Bridge (with the Chord ASIO driver installed obviously).
That should work but that’s a 2 box solution.
