I was told yes the other day by a design engineer at Rolls Royce. What he told me is that because civil and military technology tend to shadow each other a lot, there was a lot done after the 1991 Gulf War lessons in engine resistance to sand, that has mapped to volcanic ash resistance in civil gas turbine engines.
He was senior and experienced enough that I'm inclined to believe he knew what he was talking about.
