Had this exact issue, wrote a blog post about it here: https://www.ractoon.com/2016/08/wordpress-acf-pro-files-field-custom-upload-directory/

But your code would end up looking something like:

add_filter( 'acf/upload_prefilter/name=secure_files', 'secure_upload_prefilter' );
add_filter( 'acf/prepare_field/name=secure_files', 'secure_files_field_display' );

public function secure_upload_prefilter( $errors ) {

  add_filter( 'upload_dir', 'secure_upload_directory' );

  return $errors;

}

function secure_upload_directory( $param ) {
        
  $folder = '/s2member-files';

  $param['path'] = WP_PLUGIN_DIR . $folder;
  $param['url'] = WP_PLUGIN_URL . $folder;
  $param['subdir'] = $folder;
  $param['basedir'] = WP_PLUGIN_DIR;
  $param['baseurl'] = WP_PLUGIN_URL;

  return $param;

}

public function secure_files_field_display( $field ) {

  // update paths accordingly before displaying link to file
  add_filter( 'upload_dir', 'secure_upload_directory' );

  return $field;

}

Where the secure_files portion of the add_filter would be your field name instead.

Then in the secure_upload_directory() function you could use https://codex.wordpress.org/Function_Reference/get_home_path to grab the absolute path to the install location.
