Wizkids Rules!

Improved Deflector Screens (IDS from here out) -

When defending, during the compare results step if you have any active shields, cancel 1 hit/crit. Discard this card if all of your shields are destroyed.

Can IDS be used to reduce the damage from cloaked mines even though you do not roll defense dice against the mines?

Any hit or critical damages the target ship as normal. The affected ship does not roll any defense dice.

No, Mine damage is a special type of attack and only cards that specifically state they affect mine attacks or damage would apply.
