There's an entity created by another module and I'd like to change some of the fields used on a listing page. Currently that page is using the entity's list builder class. Is there a way I can define a new list builder class, make my changes, and use that for this entity? I have tracked this down to where D8 get's entity definition and loads the list builder class from that. I can't find a way to alter the definitions or another way to inject a different class here.

In more specific terms, I have created an entity with ECK and want to override the functionality around EckEntityListBuilder.

You want something like this:


 * Implements hook_entity_type_alter().
function MY_MODULE_entity_type_alter(array &$entity_types) {
  /** @var \Drupal\Core\Entity\EntityTypeInterface[] $entity_types */
