@sudodus: 20.04 is the first Ubuntu version to have "maybe-ubiquity" in grub.cfg. previously Ubuntu's grub had an "Install Ubuntu" menuentry option.
From Ubuntu 19.10:
linux /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed only-ubiquity quiet splash ---
This would make the Try/Install screen redundant.
