Sure. Just make sure the drive is warm before you take it out of the container - because this is when the critical condensation happens: you take out a cold drive an expose it to humid room temperature air. Then water condenses on (and in) the cold drive.
Re-freezing is also critical, the container should contain no humid air when it goes into the freezer, because the water will condense and freeze as the container cools. A tightly wrapped bag, desiccant and/or purging the container with dry gas would prevent that.

A vacuum sealer would probably help to avoid the humid air, too.
Only if you wait for the drive to heat up before you remove the vacuum seal.
Be careful, airtight doesn’t mean it’s not moisture permeable over time.
Color changing desiccant is a good idea to monitor it.
