Deleting Autocomplete Dictionary

I apologise in advance if I’m asking for a triviality.

If I want to delete an entire dictionary created with FT.SUGADD key, what command should I use, without having to run the entire FLUSHDB?

FT.GUSADD creates a key that stores the suggestions. You can run KEYS * to view it.
Therefore, you can delete it using the general DEL command of Redis.
