To check if dvc configuration can read from environment variable or run a command during run time

[infa-amohanda]

Hi Team,

We have a dvc config file as below and we are trying to substitute my-branch with current git branch. Please let us know if dvc supports a way to substitute a variable with environment variable or can it run a command like git rev-parse --abbrev-ref HEAD during run time.

[core]
    autostage = true
    remote = s3
['remote "s3"']
    url = s3://my-s3-bucket/dvc/my-path/my-branch

Regards,
