Expanding on Juho Rutila's answer as it's too much to fit in a comment.

This is possible using dynamic blocks from v0.12, but I found the properties had to be included in a nested content block. The for_each statement is also a bit tricky, so I found it sensible to extract that into a local to make the important stuff more readable:

locals {
  isProd = var.environment_name == "production" ? [1] : []

  // Not necessary, but just illustrating that the reverse is possible
  isNotProd = var.environment_name == "production" ? [] : [1]
}

dynamic "access_logs" {
  for_each = local.isProd
  content {
    bucket  = "my-bucket"
    prefix  = "${var.environment_name}-alb"
  }
}
