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

After that run the command sudo grub2-mkconfig -o /etc/grub2.cfg

This is for the LCD Steam Deck, numbers may differ for OLED
