Question System Configuration/ Graphic Configuration not found in BIOS

[MIGCOKO]

So I am trying to reinstall my GPU (1050ti) because it has flickering in games when I move. I looked up into Display adapters and there is no Integrated gpu only my 1050ti. I wanted to enable the integrated in the BIOS but there is no System Configuration/ Graphic Configuration in advanced option. UEFI is also not available, I have legacy. I'm Lost. Any help?
