I think there is a difference between there being a universal moral Truth (ontological) vs. a particular individuals ability to know that universal (epistemological). The former doesn't necessarily imply the latter. Rejecting the latter (the ability to know) doesn't require rejecting the former (the universal). If one considers that these two are decoupled, it poses a question: how could one live in alignment to a universal truth that one cannot know. It makes me wonder, can we find meaning without certainty. Even in this age of the rejection of religious dogma, I tend to notice that people still want to cling to certainty. They are certain there is no morality (nihilism) or they are certain that morality can be found either in the study of nature (through empiricism) or reason (through rationalism). I hardly ever see anyone suggest that they humbly do not know.
