How are entities eager loaded in Doctrine?

Question

Doctrine ORM

Guys tell me, I ran into such a nuisance and I can’t google for 5 symphonies.
I get entity like this

$repository = $this->entity_manager->getRepository(Subscriptions::class);
$subscription = $repository->find(10);
$tariff = $subscription->getTariff();

The bottom line is that when I do getTariff in $tariff is the desired model, but its fields are all null (it’s clear why there is lazy loading), but how can I do eager loading? Just right now, in order for the fields to be loaded, I have to make a crutch
and call any of the getters of this model
$tariff->getCode();
for a separate code?

I tried to google for a long time, but almost all solutions for symfony 2 are outdated already ...

Tell me how to do this?

The doctrine describes that you can specify fetch=eager or fetch=lazy in link mapping, for example, as here
