Rotate GRUB by 90 Degrees so It's Horizontal

I have my grub themed but one problem is that I need to rotate it by 90 degrees so that it doesn't appear certical and squashed any more on my Steam Deck. Any help?
Solution:
Edit the /etc/default/grub file and add:
GRUB_GFXMODE=1280x800x32
GRUB_GFXMODE=1280x800x32
After that run the command sudo grub2-mkconfig -o /etc/grub2.cfg...

add fbcon something to your kernel params grub looks at it to rotate

Tried editing the GRUB to use this: GRUB_CMDLINE_LINUX="rhgb quiet fbcon=rotate:1" Nothing happened with the rotation.
