Yeah you can't cancel the results from an obstacle because it is not an attack you are defending against, but rather the damage your ship might take when it's scraped against a space rock.

What you could do with the mentioned ships however is perform the Evade action and give yourself a token before you perform a red maneuver and a stress token so you couldn't otherwise take the action.
