Completely stop field filter values' scan queries by Metabase

We're seeing these type of queries (field filter values' scans) at different times even though we've chosen these to run once a day during 5am IST. These queries starts our serverless Databricks warehouse compute (even multiple clusters at times) - leading to higher costs.

We'd wanna either completely stop these queries and do it manually as needed, or more control on when to run it (say weekly/monthly once).

Can anyone please help me understand how to achieve this?

Yes, we're using the exact same settings. This is the driver version we're using rn - Release v0.1.0 · db-caioishizaka/databricks-sql-driver · GitHub

why "SELECT 1" queries get triggered and how to disable these completely? @Luiggi if you could guide please, this is leading to higher compute costs for us

please post where you're seeing this. It's probably a connection checker
