Deleting SAT scores?

I tried finding this online, but couldn’t find anything. How do you delete your score after getting results?
This is because some of my colleges require SAT to be sent, and my SAT score decreased by 100pts my most recent time.
I want to get rid of this so it won’t hinder my application.

You can’t delete SAT scores. They’re permanent.

ACT you can delete scores, as long as they were on National Test Dates.

this sucks, as my score dropped. I know schools consider the highest, but will a drop of 100pts look bad?
