The list of schools that require all tests is…?
I know of 3, and all three say your highest score is mostly what they “consider/give the most weight”
OP, if you’re applying to one of the 3 of the 2,000 colleges in the US, and are worried about $13 when applying to $40K/yr colleges, or that the schools won’t do what they say and consider your highest score, and think 1 point is meaningful, then yes, take the time to cancel the first score. And be sure to wait a few weeks before requesting any scores, even though most apps are due in about 6 weeks, with holiday.
I wouldn’t.
