Just don’t show up. There will be no score given. It can’t be reported becasue you would have had to select schools in advance to send it to. Yes, you can pay to take in a new date.
College Board treats a failure to show up as a cancellation. It will send absolutely nothing to any college (or others) to to even indicate you ever signed up to take the test. It does not give a refund but you can change to another test date after not showing up by paying a change fee (used to be $19 but don’t know if it is still that)
