its a different behavious listed on DB document, I dont think you are looking for this one.
Behavior change when dataset definitions are removed from Lakeflow Spark Declarative Pipelines
An upcoming release of Lakeflow Spark Declarative Pipelines will change the behavior when a materialized view or streaming table is removed from a pipeline. With this change, the removed materialized view or streaming table will not be deleted automatically when the next pipeline update runs. Instead, you will be able to use the DROP MATERIALIZED VIEW command to delete a materialized view or the DROP TABLE command to delete a streaming table. After dropping an object, running a pipeline update will not recover the object automatically. A new object is created if a materialized view or streaming table with the same definition is re-added to the pipeline. You can, however, recover an object using the UNDROP command.
