postgres auditing truncates and deletes on tables

for an RDS Aurora PostgreSQL v11.7 database I want to setup DDL and truncate and delete auditing.

I am setting log_statement to DDL, to log all DDLs (this excludes truncate statements). I also want to setup auditing only for deletes and truncates on tables. I don't want to set log_statement to all, as this would fill up my logs.

Checking in pg_audit, it supports write class which includes delete and truncate, but it also includes write/update and copy which I don't need.

Is there any way to setup auditing to audit DDL plus deletes/truncates only using pg_audit/native auditing?
