Can I add an entry to a post/topic that cannot be changed?
Can it be js/html?
Listening to your advice, I decided to learn how to create plugins. According to the api documentation I see that i can update the post (PUT Update a single topic) , but is it possible to update the post that couldn’t be changed ?
I don’t mean the whole post, but only the part I sent through the api ?

You could lock the post (like what I did with yours). That should prevent users from editing any part of the post.
You can then update the post via the API with any admin user.

But blocking the post means no discussion. It misses the goal…
Can I sort my post by tags? If so, how?

Your post is locked, yet you can continue replying to this topic. So not sure what do you mean…

Okay, you’re right. Can I sort post by tags?

Topics can be sorted and filtered by tags, individual replies cannot.
