Yes it is. I have it set up to allow both input and textarea fields for a plugin. I use it to shoe input and textareas to allow copy and paste of shortcodes from the editor for my CPT.

<?php 

add_filter('acf/prepare_field/key=field_619663d258c1e', 'shortcodes_messages', 20);
function shortcodes_messages($field) {
  global $post;
  if (is_a($post, 'WP_POST')) {
    ob_start();
    
    // I generate message here
    
    $field['message'] = ob_get_clean();
  }
  return $field;
}

add_filter('wp_kses_allowed_html', 'allow_input_in_acf', 20, 2);
function allow_input_in_acf($tags, $context) {
  $attributes = array(
    'type',
    'disabled',
    'checked',
    'style',
    'name',
    'value',
    'class',
    'id',
    'style',
    'readonly'
  );
  if ('acf' === $context) {
    if (!isset($tags['input'])) {
      $tags['input'] = array();
    }
    foreach ($attributes as $attribute) {
      $tags['input'][$attribute] = true;
    }
    if (!isset($tags['textarea'])) {
      $tags['textarea'] = array();
    }
    foreach ($attributes as $attribute) {
      $tags['textarea'][$attribute] = true;
    }
  }
  return $tags;
}
