How to add simple processing in symfony config

I am trying to create a simple processing code to Symfony configuration.
Here is the final effect I want to do (config pseudocode):

# config/packages/monolog.yml
monolog:
  handlers:
    debug_log:
      type: '%env(LOGS_ROTATE) > 0 ? "rotating_file" : "stream"%'
      max_files: '%env(LOGS_ROTATE) ?? null%'
      ...

The idea is that if LOGS_ROTATE env is set to a positive number, type should be rotating_file and max_files should be that number,
otherwise type should be stream and max_files should be skipped

Is it possible to do that?
I was considering using env processors, but those cannot take any parameters,
and using hardcoding config values inside such a processor feels bad.

edit:

I also tried to use symfony expression language, but got an error:
There is no handler class defined for handler "@=%env(logs_rotate) > 0 ? rotating_file : stream".

monolog:
  handlers:
    debug_log:
      type: "@=%env(LOGS_ROTATE) > 0 ? rotating_file : stream"
