The gpio_aaeon driver was added in more recent kernel versions. You would need to update the kernel after installing elementary with
sudo apt install linux-generic-hwe-20.04
To solve it until you install elementary, you need to press e when the "Install elementary" grub prompt appears and go to the line that says
quiet splash and write instead
quiet modprobe.blacklist=gpio_aaeon splash. Then you can continue to boot the system.
