The requirement is to update the score inside the scores array where the type is quiz and the score is 90. So, the query would be: -

db.mycollection.updateOne(
   { "_id": 1 },
   {
     $set: { "scores.$[element].score": 95 }
   },
   {
     arrayFilters: [ { "element.type": "quiz", "element.score": 90 } ]
   }
)

In the above query, $ is a positional operator.
