secure erase is the only way to clear all sectors on an SSD but at that point you're just relying on the manufacturer's implementation (and past experience from encryption has ruled that to be a derp).

an easy alternative is just to encrypt the drive using software-based encryption and just delete the key. Windows 10 has now stopped relying on hardware-based ssd encryption because it was found some of it was just garbage.

Edit: Additional caveats: some drives can move data in and out of the non-system viewable area and dead cells cannot be written if they're no longer viable so data can still remain there.
