Install arandr (gui) and from there you can set your primary screen and after that there is a option to save configuration in a file. Use that and store file in your home directory -> yourfilename.sh
then use cmd : chmod +x yourfilename.sh
and add the cmd to your default shell -> sh yourfilename.sh

#!/bin/sh
xrandr --output VGA-1 --off --output HDMI-1-1 --primary --mode 1920x1080 --pos 0x0 --rotate normal --output DVI-I-1-1 --off --output VGA-1-2 --off

For grub, you don't. Unless there's an option in your UEFI settings/BIOS, there's no way to impact where grub shows up.

For the kernel you can try https://www.kernel.org/doc/Documentation/fb/modedb.txt - specifically "e" and "D"
The output names are the ones you find in the xrandr output.
If the desired output is on the other GPU (Possible? Likely?), you can utilize "fbcon=map" to make sure that the console is bound to the desired framebuffer device
