A:AnswerThe integrated and dedicated graphics "cards" in laptops are not upgradeable unless you were to purchase an older laptop with an MXM slotted graphics card (that technology has long since passed in lapptops in everything but super high end laptops with desktop cpus).
The only available option for current technology laptops is to purchase an m.2 pcie adapter card and have a desktop gpu attached to it, which will require another power supply and in most instances, the use of an external monitor, unless you have the ability to MUX the external gpu to the internal screen.
You could also go the route of an external gpu box, the majority of which are based on usb-c thunderbolt, with an occasional mini displayport sprinkled in, of which 90% will require the use of an external monitor.
