I've never done this but according to the [ArchWiki](https://wiki.archlinux.org/title/Securely_wipe_disk#shred) you should run

    shred -v /dev/sdX

to write random data to the drive. You can also run e.g.

    shred -v /dev/sdX1

to wipe only a single partition. You can figure out the right device/partition ID by running `lsblk` or `df`. The `shred` command is part of GNU coreutils so it should available everywhere.
