Figured out how to automate it in a janky manner - details below for posterity. Still interested in getting grub to output to the LCD with keyboard input. When only letting grub see "console=tty1" in the bootargs, it spits out "error: no suitable video mode found." on the serial console right before displaying the boot menu.
boot.txt
You might need to change the "1:1" in the "load mmc" commands for your setup - for testing I was booting off an sdcard. Also note your paths to grubaa64.efi (BOOTAA64.EFI) and dtb file may be different.
grub.cfg
As others online have noted, rebooting has issues but otherwise it seems to work great.
Here is my boot log too in case it might help someone:
