if memory serves no it won’t be changeable as the gpu chip is soldered to the graphics card. You can however try (or get someone to try) to reflow the original card. I’ve had good luck with that. Do NOT try to do a reflow in your oven or with a tea light. Those typically cause more damage than good. You need a reflow machine (very expensive) or a good quality temperature controlled hot air reflow workstations. Good luck! :-)
I'm sure this is resolved already but for all future dyi persons... I repair apple computers for a living. Rob is correct. The anti glare version (silver around the LCD) has the wifi/Bluetooth on the supper drive in outer and the glossy version (black around the LCD with glass protecting the LCD) have the wifi/Bluetooth in the black clutch protective area under the words "MacBook Pro".
