Hello @Vera! Welcome to the Community. I believe this would fall under a tier-1 build, since based on your wording it sounds like you already have a drive with the OS installed on it, which is the main difference between tier 1 and 2. Technically speaking OS related setup is part of tier 2, but I doubt service would have a problem installing the drivers since you already have an OS, but I think that would be at their discretion.
