Can't drop an NDB database because the storage engine is unavailable

I tried to set up a MySQL cluster and failed. I finally got it switched back to standard MySQL, but now I have an ndbinfo database that I cannot drop. It causes my automysqlbackup cron job to report errors.

mysql> drop database ndbinfo;
ERROR 1286 (42000): Unknown storage engine 'ndbinfo'

Is there any way to manually remove the database? Or maybe a procedure that I do not know about? I did not see 'ndbinfo' referenced anywhere in the MySQL database. It's on Ubuntu Server 22.04 from the MySQL APT repository. Output from mysql --version:

mysql  Ver 8.0.33 for Linux on x86_64 (MySQL Community Server - GPL)
