I disagree with your PR @jrvoisin. Disabling client-side paging globally requires pagination_client_enabled: false. The opposite will enable it and that's not what we want when we need to disable it.

I think there's a misunderstanding @vinceAmstoutz, because this part of documentation precisely shows how to configure API Platform to let the client enable or disable the pagination with the query parameter pagination.
If pagination_client_enabled is set to false (the default value), it will not be possible to enable or disable pagination from the client.
When we want to be able to use the query parameter as below, pagination_client_enabled as to be set to true :

The pagination can now be enabled or disabled by adding a query parameter named pagination:

GET /books?pagination=false: disabled
GET /books?pagination=true: enabled
