Hello. In Hong Kong, we are creating a program for evaluating the pre-release services. What should we do if certain participants who were chosen at random have trouble understanding our evaluation? Can we simply let them respond to the inquiries without obtaining their informed consent?

Welcome.

I appreciate you providing these details.

You can't, sorry. Respecting participants is one of the most important ethical rules for evaluators, which requires you to give all participants adequate information about their rights and responsibilities during the evaluation process as well as particular accommodations for those who are unable to comprehend it.
