Replacing GPU on an Hp laptoo

Hi, i had bought an Hp 15/bw 020 nm ( on amazon its a Cuk 17 smth model)
With amd apu a12 9720p 8gb ram 1tb hard drive and a radeon 530 gpu 2gb ddr3 ( there is a version of 2/4gb Gddr5 memory).
So i was thinking is the replacement of the gpu possible here? This idea is just a backup if they dont want to take the laptop back. Ty infront i hope i wrote this to be understadable.
