I tried to turn off TRIM ("discard") on my ext4 filesystem, but I did not succeed.

I tried to add nodiscard option into /etc/fstab, but I can still see this:

# tune2fs -l /dev/md2 | grep discard
Default mount options:    journal_data_writeback user_xattr acl discard

OS is GNU/Debian, and the disk is an SSD.

the command to remove "discard" is this
tune2fs -o^discard /dev/md2
