Even in org.hibernate.persister.entity.AbstractEntityPersister.createEntityLoader(LockMode, LoadQueryInfluencers) there is comment about it

protected UniqueEntityLoader createEntityLoader(
			LockMode lockMode,
			LoadQueryInfluencers loadQueryInfluencers) throws MappingException {
		//TODO: disable batch loading if lockMode > READ?
		return BatchingEntityLoaderBuilder.getBuilder( getFactory() )
				.buildLoader( this , batchSize, lockMode, getFactory(), loadQueryInfluencers );
	}
