For those who need this functionality, a temporary solution could be the following:

locals {
    apiEnvVars = tomap({
        ENV_KEY_1: "ENV_VALUE_1"
    })
}
resource "null_resource" "example_api_env" {

    provisioner "local-exec" {
        command = <<EOT
        aws appsync put-graphql-api-environment-variables \
            --api-id ${aws_appsync_graphql_api.example.id} \
            --environment-variables \
            '${jsonencode(local.apiEnvVars)}'
        EOT
    }
    triggers = local.apiEnvVars
}
