Is there a way to compress a JSON file with Terraform?

Question

When generating JSON document types using Terraform (e.g. for policy documents) it will default to providing nice indentation, like:

{
    "Version":"2021-01-27",
    "ArrayOfThings": [
        "Thing",
        "OtherThing",
    ]
}

However, some document types in AWS have limited sizes. Is there a way of controlling what the output formatting for the documents generated by Terraform is (i.e. not the terraform --json output, a step in the document itself)?

Ideally I'd like to use the Terraform provider (which has a json output) and then connect that through a minifier, so it would end up being published to AWS as:

{"Version":"2021-01-27","ArrayOfThings":["Thing","OtherThing"]}

The Hashicorp terraform rule that I'd explicitly like to use this on is the aws_iam_policy_document one, which has a .json output. Is there an equivalent .jsonCompressed or another Terraform rule that I can use the output of aws_iam_policy_document to minify the JSON output?
