Can I use something like the SSD TRIM command on a SD card?

Can I use something like the SSD TRIM command on a SD card? SSD flash hard drives have started to support TRIM in order to avoid the slowdown that occurs after a while.

"On Linux:

blkdiscard on the unmounted block device (e.g. /dev/mmcblk0) to discard all blocks (renders data inaccessible through normal means, but does not promise to securely erase them).
fstrim (on the mounted file system) if you want to keep the data but discard the blocks that are unused."

"First backup all your data on the SD card. Then you can use the SD Formatter tool and in options select FULL (Erase):
