I don’t think so. Instead, any query done from your APP to retrieve data will count as an update.
With BT as you know, the entire data is not loaded into APP so you need to create queries to retrieve specific data and work with it. This is why there is no a rollup column (native) in this scenario for example.
But just a curiosity: how many rows will your table have: 50k, 80k or 150k+ rows?
If your tables are going to be used to be read-only, there are other options to do it (and cheaper I think).
