How can you remove another modules events?
Remove the event subcriber service from the container:

my_module/src/MyModuleServiceProvider.php

namespace Drupal\my_module;

use Drupal\Core\DependencyInjection\ContainerBuilder;
use Drupal\Core\DependencyInjection\ServiceProviderBase;

/**
 * Remove the foo event subscriber.
 */
class MyModuleServiceProvider extends ServiceProviderBase {

  /**
   * {@inheritdoc}
   */
  public function alter(ContainerBuilder $container) {
    $container-&gt;removeDefinition('foo_event_subscriber'); 
  }

}


You find the service name in the MODULE.services.yml file of the other module.
