Can you choose disk location for topic event log?

[Andrew9317]

We have a use case where we want 90% of topics written to ephemeral ramdisk since persistence doesn't matter for these and the data is required to not be stored on disk, but we require a few select topics to be persistent and stored on disk. Is there a way to have individual topic locations in one broker or do we need to spin up a second broker for the ones we need on file system?
