Disabling Aria INSERT log in MariaDB

When I bulk INSERT into an Aria table, it creates a copy of the INSERT in a series of log files (aria_log.%). It can lead to full disk and crash of MySQL. As I understand, Aria keeps a redo log for TRANSACTIONAL=1 only, and the default behaviour is TRANSACTIONAL=0. I also created a table specifically with TRANSACTIONAL=0, but the same behaviour. I use Aria for a sort of backup, as it is faster than InnoDB on HDD, and do not need transactional/crash-safe behaviour. How can I disable Aria logging and only writing into the table?
