Mate just keep it and enjoy it, next set of cards for sale will probably be same model with another manufacturers sticker on it for £100+ more. So be happy you got one , it took me almost 2 months to get a 3090 and days and weeks wasted in time trying to find one in stock that I wanted and finally after 2 months got the pair of 3090s I wanted at a price that I was willing to pay for them and no they were not FE models. I wish I got the card I wanted for the extra you paid, I paid a lot more for mine in the gouging rate, one of the cards I paid £1700 and the second one £1580 same cards from same retailer and thank god they allowed the 2nd one at £1580 because days before I purchased at the right price and they let it slip.
Same retailer a few days later another card came up different brand and knew people wanted it on the forums Aorus Extreme 3090 and was priced again wrong, £1670 I purchased it but this time they said sorry wrong price and we can't let it slip this time and said to buy it again at correct price £1750.. I didn't but wanted to get it and help someone out here for one (same price I paid for it with the invoice) and then thought £1750 is a lot of money if I get stuck with it and have 2 already and I even offered one of mine to help out forum members earlier in the week for cost I paid £1580 not the £1700 one and they didn't bite then I sold the game code and Geforce code for £40 , knocked the card to £1540 and they still didn't bite for a card that sells for £1700, so I removed it from sale.
So do yourself a favor keep it be happy and then you won't be stuck for months trying to get one at the fake MSRP price that was only for a few cards from AMD as Nvidia did but difference is Nvidia still make the FE , AMD will not have anymore of these reference cards with their branding on it. You will thank me later
