Pagination 301 redirecting page 1

Question

I am using the paginate_links function in a custom theme to generate the pagination links which is working fine however the page 1 link which is /blog/page/1 gets a 301 redirect to /blog/.

This is the same content and page so is fine but it seems like an unnecessary redirect so I was trying to find a way to change the page 1 link to just to be /blog/.

I've had a search around and feel like something could be done in the base variable rather than putting in custom pagination but of the things I've tried it breaks the pagination.

$current = max( 1, get_query_var('paged') );    
$big = 999999999;
        echo paginate_links( 
          [
              'base'         => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
              'total'        => $update->max_num_pages,
              'current'      => $current,
              'format'       => '/blog/page/%#%',
              'show_all'     => false,
              'type'         => 'plain',
              'end_size'     => 4,
              'mid_size'     => 1,
              'prev_next'    => true,
              'prev_text'    => '<i class="fas fa-arrow-left"></i>',
              'next_text'    => '<i class="fas fa-arrow-right"></i>',
              'add_args'     => false,
              'add_fragment' => '',
          ]
        );
