Predator Helios 300 i7 8th gen PH315-51 Not Detecting the GPU

I have bought the device 5 days ago, then i checked the device and everything was good, so I started updating everything including BOIS.
after I finished updating the GPU was not detected by the system even in Device Manager > Display adapter. it only shows the integrated Intel GPU.
I performed the following action, but it didn't work at all. Even GeForce is not detecting anything

1. reset windows 10
2. I tried to downgrade the BIOS, but it didn't work "the installed version is newer than the one you want to install" < something like that.

It could be the dreaded error 43.

A while back Nvidia released a bad batch of GPU chips that were faulty.

In my opinion the best bet is to send it to Acer under warranty and have them replace the motherboard.
