I'm no expert, but my experience in the order of importance;

1. Having the camera and housing in an air-conditioned room before hand, and sealing it in the room.

And that just increases the likelihood of condensation.

2. A small silica gel packet in the housing.

That helps.

The root cause here is a cool camera in warm water.   The coolness of the camera body causes humidity already in the housing to condense.

What has helped me:

1. Do NOT allow the camera to go into the housing cooled by A/C.   Better to have everything at the water temp when you go into the water.   Thus you want to leave the camera in a non-air-conditioned environment, preferably with a gel packet.

2. Put antifog chemical on the glass involved.

What has hurt is diving in cooler depths, then coming up to the warm shallows.   Only a gel packet is likely to be completely successful.
