Test cards with ecommerce gateway

I have a Business account. I am hoping to enable the Revolut gateway in woocommerce. The guidance says that I should first setup a Sandbox account. But it is impossible to generate a Sandbox account and I am not sure that I need it on an already working site. I have spend days trying and am close to giving up.

My site is already processing cards via Stripe. Can I use the Revolut test cards to check the Revolut Production gateway without first using Sandbox?
