Welcome to ISO audit slogan

No need, they are hired by you, you are his customer, you are his God. Make no mistake.

If you want to hang a banner, all you need to do is express your intention. What the audit company is most afraid of is that your standards are too poor. As a client, they want to issue you a certificate, but they are afraid of damaging their own brand. So as long as you do a little better, find someone who understands the system to answer the questions correctly, and lead the reviewer to the aspects you want him to know, and avoid the aspects you don't want him to know.

Everything is OK.
