Thanks for the answer! So do I assume correctly then that things like using the 'overwrite data'-option when running BleachBit, or wiping/erasing partitions or disks with zeroes in GNOME Disks or GParted actually does zero the data like normal, even if the quirk is enabled?

What if you try to wipe a NVME-drive for which this quirk is enabled by default in the kernel? Does that mean that even if you used something like the 'erase device' function in GNOME Disks on said drive, it would in fact not actually completely zero the drive? What if you use GNOME Disks to wipe a partition on said drive?

Or does this quirk refer to an entirely different operation?
