Assuming you've configured log.dirs to use specific volume mounts, then no.
The contents of the directories for that value must be topic-partition folders, not a parent folder of all volumes where it would be more possible to dynamically add directories.
Drives may be hot swappable on the physical server (or VM), yes, but you'll still need to edit the Kafka property file to include the new mount path, and restart the broker.
Also, if you add new disks, Kafka will not rebalance existing data, meaning you'll still have discs that are 90% full. In any environment, you'd need to create/acquire a new, larger disc, shutdown the machine, replicate the disc, then attach the new one, and restart.
