I just did a quick look and I found this at the beginning of the ACF code that determines the current post ID

$preload = apply_filters( "acf/pre_load_post_id", null, $post_id );

This can be used to determine the post ID, if you return any value it will override ACF looking for the post ID.

I do not know the specifics of what you need to do off the top of my head… and it could get complicated and there are a number of factors to consider.

Just as a for instance, you would want to return the value for get_option( 'page_for_posts' ); only if you were not inside the main loop and you actually want to show a field for the current post. I’m not exactly sure without doing a lot of testing how to determine this.

this might work, but it is only a guess

add_filter('acf/pre_load_post_id', 'your_filter_name_here', 10, 2);
function your_filter_name_here($value, $post_id) {
  $queried_object = get_queried_object();
  // queried object will be page for posts if it is the blog page
  if (is_a($queried_object, 'WP_Post') && $queried_object->ID == get_option(page_for_posts')) {
    $value = intval(get_option(page_for_posts'));
  }
  return $value;
}

There is also a filter at the end of the ACF code to determine the post ID that can potentially also be used in some way.

$post_id = apply_filters('acf/validate_post_id', $post_id, $_post_id);
