How to register custom Hydration strategies?

[MatthiasKuehneEllerhold]

I'd like to use php8.1 built in enums in doctrine backed entities. According to https://www.doctrine-project.org/projects/doctrine-laminas-hydrator/en/3.3/enum-strategy.html#using-enums-with-php-8-1 I need to create and register a custom hydration strategy for each enum I want to use.

Is there any configuration key where I can easily register them or do I have to use a Delegator on the DoctrineHydrator?

No, there is no specific configuration key, as currently there is no way to have hydrators being automatically created by DoctrineORMModule. Note that the hydrators are entity-specific anyways, as the properties for which you are registering the strategies will differ between different entities.
