grub-install complains that system doesn't support EFI variables, but it installs correctly into EFI partition. Solution is to use another tool, and add GRUB UEFI entry grub manually. From Windows:

bcdedit /set "{bootmgr}" path \EFI\debian\shimx64.efi

Boot to Windows.

1. Settings –> Update & Security → Recovery → Advanced Startup → Restart Now
2. Troubleshoot → Advanced Options → UEFI Firmware Settings

To use 2 external monitors:

1. BIOS
   1. select “Discrete graphics”
   2. disable Secure Boot (to use nvidia modules)
2. Linux
   1. sudo apt install nvidia-tesla-470-driver
