Problem:
I would like to change the position of where the comments are displayed,
and display them somewhere inside a content template.

I thought about one type of solution, I added a shortcode in functions.php:

add_shortcode( 'display_comments', 'display_comments_shortcode' );
function display_comments_shortcode() {
comments_template();
}

then I added the shortcode somewhere inside the content template, but the comments where displayed at the top of the page, above everything in the page, and not where I located the shortcode.
Solution:
The WordPress function comments_template() will output the HTML codes directly, in the shortcode PHP function, you will need to setup it as return, so you can modify your codes as below:

add_shortcode( 'display_comments', 'display_comments_shortcode' );
function display_comments_shortcode() {
 ob_start();
 comments_template();
 $res = ob_get_contents();
 ob_end_clean();
 return $res;
}
