It’s possible through the option card slot but in no way cheap at all.
But the console will clock through its option slot (Waves SoundGrid or Dante).
You could then clock from these cards using external means but with the cost and hoops you need to jump through, it really makes no sense unless you’re already using these cards for another purpose.
I should add, the console sounds beautiful and imho clocking, conversion, and signal paths are of no issue.
