Table materialization

The problem I’m having

dbt model sql file + yml, the properties file stores column metatada and for esch column comment a new version is created.

The context of why I’m trying to do this

Materialization table, dbt run model with 300 columns scheduled 4 times/day. Each run creates 300 versions in history.

What I’ve already tried

I’ve tried to override persist_docs (which is set on true at peoject level and I cannot change that) and now I’m thinking about writing a macro that would alter all columns in just one operation but I’m not sure if it is a good approach.
