Hi,

see hook on documentation, you just need this in B entity as hook

    public function afterRemove(Entity $entity, array $options): void
    {
        if ($entity->get('aId'))
        {
            $a = $this->em->getEntityById('A', $entity->get('aId') );
            
            if ($a){
                $this->em->saveEntity($a, [
                    'modifiedById' => $this->user->getId(),
                ]);
            }
        }
    }​
