Sorry I missed that part of the requirement completely…
We will need to go with another method.
Add this PHP snippet:
add_filter( 'generate_footer_entry_meta_items', function() {
return array(
'date',
'post-navigation',
);
} );

Then this CSS:
.blog .post .entry-content, .archive .post .entry-content {
border-bottom: 1px solid #000;
}
