Did you already tried removing the CMOS battery?
Try this test to reset BIOS -
Disconnect all power supply and Battery.
Press power button for 30-45 seconds.
Connect and start it up.
If that doesnt help, try pressing the NOVO recovery button and see if that displays something.
Also, try connecting to an external display using HDMI and see if that works.

First you cant disable the integrated graphics on a stock BIOS unless you have Modded BIOS.... The reason the integrated graphics cannot be disabled because its the graphics which is driving the display & not the NVIDIA one.... Even if you try to disable the integrated graphics(Intel HD 4600) you cant boot up the laptop..... The NVIDIA graphics is hard wired to the integrated graphics card(Thats why you can disable discrete GPU but not the integrated one)..... It can be overcomed by turning off the laptop removing the power cord & pressing power button for 30 seconds this is called as power cycle.... And then remove the CMOS battery by unscrewing your laptop...

I am sorry guys i've tried all those and it didn't help sorry, so i've sent it to a computer shop and the agent told me that it needs a new bios file which is hard to find the source in the internet bcuz my laptop's version of bios is new and he dont have it so it will need someone with the same laptop to extract and upload his bios and i download it and it should work.
If anyome of u guys can help with that i would be greatful

Clearly where you took it is really clueless. The bios doesn't get corrupted or damaged by making a setting change.
See if there is a Lenovo Service center or a true repair center for laptops.
