Dedicated graphics not detected on Acer Aspire 515 - 51G - 53

I have a couple of years old Acer Aspire 5 A515-51G-53 with a dedicated graphics card Nvidia Geforce MX150 2gb. The problem is that the laptop no longer uses the dedicated graphics and doesnt detect the MX150. It doesnt show on device manager, new drivers cant be installed and the GeForce experience does not work. I have tried updating the chipset drivers to no avail. This problem has persisted for a while now. There are some threads on the internet on the topic of the graphics card disappearing on the A515 series but none of them offer a solution. Please help me to get the dedicated graphics working again!

Could it be a BIOS problem? Heres my current bios:

InsydeH20 Rev 5
Bios version 1.12
Gop driver 9.0.1066

If you're willing to risk disabling the machine, there is an updated BIOS available at this link which reportedly addresses vbios nv17s nvidia graphics adapters. Jack E/NJ
