A different route to the same conclusion: if you buy the fine tuning argument (or the argument from psychophysical harmony, or similar) then fine tuning is strong empirical evidence for at least one stance independent evaluative fact. Reason: if the fine tuning argument works, the hypothesis that fine-tuning confirms isn’t just theism; is the conjunction of theism *and* the hypothesis that life is objectively valuable (or similar). So, if fine tuning is evidence for theism, it’s evidence for value realism too. (And once that stance independent evaluative fact is let through the door, there aren’t many reasons for skepticism about the existence other evaluative facts.)
