No, you don’t need to set those on DBR 7.3 and above.
From 7.3+ Databricks already uses the newer Hadoop S3A connector by default, so those com.databricks.s3a.S3AFileSystem settings are not part of the default config and shouldn’t be added.

If 
they are present I would assume it has been added manually, and removing it should cause no issues
