My Graphics shows 7 MB, Mojave

Processor: Intel i3

So, I recently upgraded from High Sierra to Mojave, but unfortunately my graphics memory become 7MB. I’ve GTX 1050Ti 4GB OC edition. It was working fine on High Sierra after some workaround. So, is there any way to get my nVidia graphics driver back on Mojave (as I’ve seen many people says it’s not possible) or if not, my Intel’s integrated UHD graphics driver.
