Yes!
Pi-hole supports query-type dependent regex blocking.
A regex like
.;querytype=OTHER
should block all queries with type OTHER. As this query type is becoming more and more frequent now, we're discussing internally how to go forward. We'll likely just add this new iOS query type as an additional record in the next release of Pi-hole. Note that this regex above will then need to be updated as the type 65 will not be covered by OTHER any longer if it gets its own assigned type.
