GPU issue on laptop

Hi! So, I have finally made my first Hackintosh, mostly so I could use XCode. My problem right now is that it doesn't see the external GPU, so I can't use the HDMI or DisplayPort port.
Is there any ways to enable it?
Specs are: i7 4700MQ (HD Graphics 4600)
GTX 770M
macOS Catalina
