Is there any way to disable title？

We consider these as posts, but Discourse’s mechanism requires a title for each post.

I assume you mean topic, not post?

@Haoliang

if there is a method to hide the title display entirely

You can hide what you want with CSS. How to do that depends on what you want to do exactly, because hiding titles on Discourse seems a weird idea
