If you're set on keeping the routers in a NSSA you could simply
disable redistribution into the NSSA area by adding
'no-redistribution' to the area config.

This will effectively keep type 5 LSAs from being advertised into the NSSA.

Realistically it makes more sense to turn the areas into totally
stubby areas. I don't see what benefit you gain from keeping the
routers in a NSSA.
