Default apps.

How I change that "chrome" to "none"?

Like this!

My UX is messed up because of that chrome thing. 

After clear default> reset app preference. 

Finnally today Samsung team gets log file to do something.

AFAIK we can't choose "none" for browser app, at least after One ui 5 update. I think it was possible earlier.

No that not possible. I have many thing on chrome but without sync.
