Conditional turn off features on apollo router yaml

Router
1

I have an environment where I need to turn off observability depending on the environment, but I can manage it via an environmental variable. The problem is given how the variable is read, it is always a string, and I cannot do

exporters:
  otlp:
    enabled: false

  tracing:
    otlp:
      enabled: false

And doing something like this does not work

  tracing:
    otlp:
      enabled: "${env.APOLLO_OBSERVABILITY_ENABLED}"

Also tried to use !!bool , but the Apollo Router YAML interpreter did not like it.

Any suggestions?

My aim is to avoid having multiple configurations for router
