In his book "Electronic Classics", Andy Emmerson recommends spraying (or brushing) asbestos generously with clear varnish. This has the efect of holding it together, and thus minimising the risk.

Of course it reduces its heat insulating properties, so it's perhaps not a good idea in the DAC90 where (if I remember correctly) the dropper is a snug fit in the asbestos lined housing.

In the DAC90 I would suggest the best approach would be to leave it alone. If you don't disturb it, it should be fine.

If you need to disturb it, spraying it with water should help keep reduce the dust. Maybe you can put the whole section in a bowel of water and work on it in the water?
