In wanting to clear up disk space on my SSD btrfs partition I discovered I had ~11GB used in old docker subvolumes.

I uninstalled docker last year after teaching myself how it works etc. And I’m sure I deleted all containers via the docker cli. Is it just a matter of using rm to delete those directories or should I use YAST2 Partitioner to delete them since those subvolumes are listed there?
Thanks…
