Per the arch wiki, https://wiki.archlinux.org/title/Solid_state_drive#TRIM the correct way to verify TRIM support for SSD drives is with lsblk --discard.

I should also add as a note that if a user encrypts their disk with LUKS. Fstrim service won't work as it's disabled by default. https://wiki.archlinux.org/title/Dm-crypt/Specialties#Discard/TRIM_support_for_solid_state_drives_(SSD)
