Symfony use direct value in Environment Variable Processor

In documentation it says to define 2 YAML parameters for Environment Variable Processor to work:

parameters:
    env(FOO): 'file.json'
    app.file: '%env(file:FOO)%'

Is it possible to use file name directly? E.g.:

parameters:
    app.file: '%env(file:"file.json")%'
