Dban is for HDDs, not SSDs. Since SSDs use a different technology for writing data (it writes to a new block each time), it can keep some data on the disk even if you fully rewrite it.
Secure Erase is officially supported by manufacturers and works most of the time since it resets the memory and takes seconds. No reason to spend hours filling SSD with zeroes.
If you encrypt your SSD, all you need to do is perform Secure Erase (ideally) or at least remove the partition. If there was still someone to retrieve the data, he would have to guess the password, which should be over 20 characters long (recommended by VeraCrypt).
