Secret manager, environment variables and default values

[j1cs]

I'm using gcp secret manager to store sensitive information; for example to know the password of the database I use ${sm.database.password}. I would to know whether there is a way to have an alternative value using from a env variable as well as default value; somethings like: ${sm.database.password:ENV_VAR:myPassword}
meaning: sm.database.password = secret manager variable
ENV_VAR = environment variable
myPassword = my local db password
