apply_filters ( 'infinite_scroll_archive_supported', bool $supported, object self::get_settings() )

Notes

By default, Infinite Scroll is only active on your site’s home page, on archive pages, and on search pages. You can, however, use the infinite_scroll_archive_supported filter to add support to other pages, like WooCommerce’s Shop page in the example below:

function tweakjp_custom_is_support() {
    $supported = current_theme_supports( 'infinite-scroll' ) && ( is_home() || is_archive() || is_search() || is_shop() );
     
    return $supported;
}
add_filter( 'infinite_scroll_archive_supported', 'tweakjp_custom_is_support' );
