Reply To: Change mode pagination (Infinite Scroll)

You can hide that by using the following CSS in Additional CSS section

.site-content nav {
    display: none;
}

In the functions.php bottom you have to paste the following code for infinite scroll to work:

function iop_infinite_scroll_init() {
    add_theme_support( 'infinite-scroll', array(
	'type'  => 'scroll',
        'container' => 'content',
    ) );
}
add_action( 'after_setup_theme', 'iop_infinite_scroll_init' );
