Never had that one, but from the docs you apparently can select it, say you do not want the free thing and it will never come back and also not be replaced with an ad for unrelated products. Edit: until you apparently log in on a new device and if it is new enough you get the same offer.
Still only once per account though. If you have a family setup it's actually only once per family even, I'd imagine it reverts back to once per account if you leave the family.
So basically, if you don't like seeing it, activate it and then immediately cancel it, and it should never come back.
Interesting, I haven't checked with the rest of the family, but would that also mean that the trial is family-scoped so that you can't all trial it individually?
