I've heard people talk about Revolut in the UK, and you can create a virtual debit card

Unless their terms have recently changed, VCCs are also supported.

There is only one company that issues virtual credit cards in the UK, and that's Revolut.

There’s an app called curve which gives you a virtual card. The way it works is it combines all your accounts into an app and if one card gets declined it will automatically switch to the other. Now the curve card has its own card number and cvv. If I use that at checkout, will it count as a different payment method?

Basically
You pay with your curve cards card number and vcc but the money gets taken out the account you choose on the app.
Also since the billing address I would be the same as my main card - ones I’ve used to se amazon before, will i be detected?
