Undo cannot be "turned off" because without commit/rollback capability,
RDBMS can no longer manage resources and cannot observe ACID properties.
What you can do is to load files as BFILE type, which, essentially,
means that you are copying them to file system and just recording the
pathname into the database. If you use DBMS_LOB.READ, then LOB blocks
are protected by the transaction mechanism and there is nothing you can
do.
