What is the right way to set knitr options in a Quarto manuscript project?

Description

I set the the following knitr options in a Quarto file and they work in a standalone file:

knitr:
  opts_chunk: 
    include: false
    echo: false
    message: false
    warning: false

However, for the same file in a Quarto manuscript project, these options seem to be ignored no matter whether I set them in the header or in the code block. The generated HTML file always shows codes and messages. I'm not sure whether this is a bug or I should set them somewhere else?
