Как отключить deprecation log в Symfony?

Обработчик deprecation сделать первым, и добавить bubble: false

monolog:
    handlers:
        deprecation:
            type: stream
            path: "%kernel.logs_dir%/%kernel.environment%.deprecations.log"
            level: INFO
            channels: ["php"]
            bubble: false
        main:
            type: fingers_crossed
            action_level: error
            handler: nested
            excluded_http_codes: [404, 405]
        nested:
            type: stream
            path: "%kernel.logs_dir%/%kernel.environment%.log"
            level: debug
        console:
            type: console
            process_psr_3_messages: false
            channels: ["!event", "!doctrine"]
