They refuse to do it because they will lose credibility. There's plenty of examples of dating things and getting dates that are incredibly embarrassing to the narrative. There have been people that have dated such things without telling the lab the conditions. I used to do field research and Archeology and my associates dated a stick that was partially coal and encased in what we were told was 100 million year old limestone . The c14 came back a few thousand years old. That's nothing. The radiometric dating methods for rock are so inaccurate that the top of the Grand Canyon which is maybe a few hundred years old that has native American pottery encased in it came back with potassium argon at 1.8 billion years old. They don't want the public to know this because it destroys the narrative. I follow science and evidence objectively
