You can boot with a graphic UI as long as you use the Intel BDS. You
should also configure a USB keyboard in that case, and drop the
'-nographic' from the QEMU command line.
For instance,
qemu-system-aarch64 -M virt -m 512 -cpu cortex-a57 -bios QEMU_EFI.fd
-device VGA -device usb-ehci -device usb-kbd
will give you a beautiful Tianocore splash screen before launching the GUI
