If you can bypass the device's internal wearlevelling logic, then
maybe;  but it doesn't look awfully like one can.  Can you, for
example, write your own out-of-band data, or write untranslated sectors?

The problem we had was the internal ASIC getting confused and causing
the whole device to cease to function.  It doesn't look awfully like
these extra commands will help this.
