I made a featured collection slider and named it product-slider. The issue is currently 1 slider adds 12 seconds in pagespeed.insights. Can anyone help me out? Here is my code:

{{ 'product-slider.css' | asset_url | stylesheet_tag }}
{% assign background_image = section.settings.background_image | default: '' %}
{% assign background_color = section.settings.background_color | default: '#ffffff' %}

<div class="product-slider" style="background-image: url('{{ background_image | img_url: '2048x' }}'); background-color: {{ background_color }};">
  {% if section.settings.title != blank %}
  <div class="section-header text-center product-slider-header">
    <h2>{{ section.settings.title | escape }}</h2>
  </div>
  {% endif %}

  {%- assign collection = collections[section.settings.collection] -%}
  {%- assign product_count = section.settings.product_count | default: 4 -%}

  {% assign product_width_percentage = 100 | divided_by: product_count %}

  
  <div class="products-carousel js-flickity">
    {% for product in collection.products %}
    <div class="carousel-product-slider-cell" style="width: {{ product_width_percentage | minus: 5 }}%;">
      <a href="{{ product.url | within: collection }}">
       <img class="img-explore lazypreload lazyautosizes lazyloaded lazyload" src="{{ product.featured_image | img_url: 'master' }}" alt="">
        <div class="hover-actions">

I tried using every single lazyload library there is and it still doesn't lazyload (lazypreload lazyautosizes lazyloaded lazyload). Also shopify is supposed to adjust images and make better performance but for some reason when it comes to slides it doesn't. I want to add 4 slides and when I tested, it added 80 seconds which is awful.
