In place update for aws_elasticache_serverless_cache from Redis to Valkey

I have setup a redis cache like this

resource "aws_elasticache_serverless_cache" "example" {
  engine = "redis"
  name   = "example"
  cache_usage_limits {
    data_storage {
      maximum = 10
      unit    = "GB"
    }
    ecpu_per_second {
      maximum = 5000
    }
  }
  daily_snapshot_time      = "09:00"
  description              = "Test Server"
  kms_key_id               =module.cmk.arn
  major_engine_version     = "7"
  snapshot_retention_limit = 1
  #security_group_ids       = [aws_security_group.test.id]
  subnet_ids               = module.subnets.subnet_ids
}

and what I would like to do is changing the engine from Redis to Valkey.

While on AWS console this process sets the cluster in Modify Status (and updates downtime free), Terraform does a force replacement.

-/+ resource "aws_elasticache_serverless_cache" "example" {
      ~ arn                      = "arn:aws:elasticache:eu-central-1:517455374594:serverlesscache:example" -> (known after apply)
      ~ create_time              = "2025-02-18T12:49:49Z" -> (known after apply)
      ~ endpoint                 = [
          - {
              - address = "example-foobar"
              - port    = 6379
            },
        ] -> (known after apply)
      ~ engine                   = "redis" -> "valkey" # forces replacement
      ~ full_engine_version      = "7.1" -> (known after apply)
      ~ id                       = "example" -> (known after apply)
        name                     = "example"
      ~ reader_endpoint          = [
          - {
              - address = "example-foobar"
              - port    = 6380
            },
        ] -> (known after apply)
      ~ security_group_ids       = [
          - "sg-666aff0b",
        ] -> (known after apply)
      ~ status                   = "available" -> (known after apply)
        # (7 unchanged attributes hidden)

        # (1 unchanged block hidden)
    }

Is this a missing feature or how can I achieve the same with terraform?
