How to hide 'show solution' feature in the content types

Hi, I would like to measure K-12 students' digital literacy competency using H5P content types. However, I have a problem in achieving this goal. Besides the Question Set content type, other content types have 'check' button and after students' clicking the check button, they can see the answers of the question. Are there any ways to prevent students from seeing the solutions of each question?

Thank you in advance.
