Do you mean turn off the link to view comments? To do that just remove the meta-comments-link template part from being rendered:
add_filter( 'amp_post_article_footer_meta', function( $meta ) {
$i = array_search( 'meta-comments-link', $meta, true );
if ( false !== $i ) {
array_splice( $meta, $i, 1 );
}
return $meta;
} );
No, I believe they mean the button “Leave a comment” at the bottom of every AMP page … could this not be an option? WordPress is all about options and there should probably be an option to turn this off, especially if normal pages have comments turned off.
So you want comments to be enabled for the canonical post, but hidden from the AMP version? If you just want to turn off commenting altogether, just turn off commenting on the post itself in the edit post screen.
Otherwise, if you want to remove the “Leave a comment” link, use the above filter.
