Nvidia drivers compatibility (with GPU and eGPU) issue
After 1060's driver installation the system shows error 43 on GT 650M (main GPU) and simply does not display 1060 in Device Manager. 1060 runs only without any driver. GT 650's driver is also not compatible with 1060.
Is there any way to install and use 2 nvidia drivers?
When I'm turning off GT 650M via PCI in the Device Manager - Windows can't run (even in Safe Mode).
Could you please advise any solution? Any suggestions?
Thank you in advance!

If there's no way to turn off GT 650M, then modding the drivers is the only option available.
You can modify the driver for 1060 to install and detect GT 650M as well.
I don't think you need to mod drivers. I had the similar problem with Quatro P1000 GPU and GF 1070 eGPU.
Either Quatro or GF was working because of the clashing drivers.
I downloaded the latest GF drivers from Nvidia website.
I unistalled Quatro and its drivers in the Device Manager. (It got generic Win drivers so the Win still run)
Then I restarted ntb without any connection to internet to prevent Win 10 to download and install Quatro drivers (It may be not neccessary).
I Installed the GF drivers and both GPU got the same drivers and both have been working together with no problem since.
The only downside of this solution is that you lose 3D modeling programs mesh acceleration that is contained in Quatro drivers for P1000.
