In your controller action set it up like that:
  $action->config('scaffold.relations_actions_blacklist', [
    'Registrations' => ['edit', 'delete'], // only allow view action
    'Rewards' => ['delete'], // don't allow delete
  ]);

Change/add this in the appropriate place in the Template/Element/view/relations/has_many.ctp which you have copied from the CrudView plugin to your own src/ dir:

  foreach (${$viewVar}->{$details['entities']} as ${$otherSingularVar}) :
  .
