Is that a laptop? If so, what makes you think you can add a 550 to it?
Well, actually it is a laptop and it has a RX550 xD
If you have the laptop with the 550 already in it, shouldn't you be the one telling us how crossfire is working, or not?
For one thing, your documentation would tell you. If you don't have any, a quick visit to the manufacturer's website can fix that. I would look myself except you didn't see fit to list make/model.
