I've just checked each day from 10-16 September inclusive, and there simply is no business award availability on EI068 (LAX-DUB).

If a business class seat isn't available to redeem into outright using Avios, there is definitely also no business class seat available to upgrade into using Avios.

You may wish to consider using your Avios on a BA flight instead.
