This will depend on the specific threat model for the sensitive data you are dealing with, but generally files in an SSD can't be destroyed securely (and shred specifically does not help due to wear leveling).

Instead, you may want to encrypt your disk so that as soon as the key is gone it all becomes unreadable. For a bigger threat, maybe you need to follow the NIST destroy guidelines [1] to "Disintegrate, Pulverize, Melt, and Incinerate" the media.
