I am in the same situation - after rushing to place my pre-order, I realized that the CPU’s integrated graphics would be sufficient for my needs and therefore the Graphics Module I selected was an entirely superfluous addition. I had a conversation with Support about this and documented my findings in this topic.
Those who would like additional information can read through the posts, but in summary, I can confirm that the options offered to me by Support match what was written above:
It seems that the original poster of this topic has decided to keep their Graphics Module after all, but I still plan to resell mine once the 30-day return period on my order expires (on 2024-04-05T00:00:00Z). I will create a dedicated topic for this closer to that date if I have not found a buyer by then. In the meantime, if anyone with a Canadian shipping address is interested in this offer, please send me a private message so we can discuss the matter further. Thank you for your consideration.
