Tested with iso built from live-build and import ubuntu-drivers-common from focal-proposed. After installation finished, check /var/log/installer/syslog can see error log as attachment. It says "ubiquity: chroot: failed to run command ‘prime-select’: No such file or directory", because 31ubuntu_driver_packages is called by target config hook which is run before target install stage. Also tested with 21.10 iso file and will got same error message in log.
