How to configure CircleCI IaC Terraform pipeline to provision AWS Services on multiple environments?

Question

I have created a CircleCI pipeline to provision an S3 bucket on AWS.

I would like to configure this pipeline to provision S3 on multiple environments like DEV, SIT, UAT etc.

I am not sure how to configure this pipeline to run for multiple env (using different tfvars for each env)

So i would be using s3_dev.tfvars to provision dev env, s3_sit.tfvars to provision sit and so on.

Is there a way to pass a parameter at runtime (containing the env which i would like to provision) which I could check in config.yml and accordngly select the tfvars for that env and run the pipeline using that tfvars?

Please advise.
