Change Blog Post Column Section view from 2 to 3 in Impact Theme

I would like to change blog post view from column of 3 to 2. I cannot find where to edit the number in the liquid file.

{%- render 'section-spacing-collapsing' -%}

<style>
  #shopify-section-{{ section.id }} {
    --blog-posts-per-row: {% if section.blocks.first.type == 'blog' %}{{ section.blocks.first.settings.blog.articles_count | default: 3 | at_least: 2 | at_most: section.blocks.first.settings.posts_count | at_most: 3 }}{% else %}3{% endif %};
    --blog-posts-grid: {% if section.blocks.first.settings.stack_items or section.blocks.first.type == 'article' %}auto / minmax(0, 1fr)){% else %}auto / auto-flow 74vw{% endif %};
  }

  @media screen and (min-width: 700px) {
    #shopify-section-{{ section.id }} {
      --blog-posts-grid: {% if section.blocks.first.settings.stack_items or section.blocks.first.type == 'article' %}auto / repeat(var(--blog-posts-per-row), minmax(0, 1fr)){% else %}auto / auto-flow 52vw{% endif %};
    }
  }

  @media screen and (min-width: 1000px) {
    #shopify-section-{{ section.id }} {
      --blog-posts-grid: auto / repeat(var(--blog-posts-per-row), minmax(0, 1fr));
    }
  }
</style>
