Here is a breakdown of the features and purpose of Ppf.esm:

Ppf.esm is a Fallout 4 master file (ESM) used by a mod or mod-pack to introduce or modify game content at the highest load order priority. As a master, Ppf.esm provides base records that other plugins (.esp/.esm) can reference. Typical roles for a file named like this include: core content for a large overhaul mod, compatibility framework, or a patch that consolidates many changes into a single authoritative source.

If you know you do not actually need the Previs data but a mod stubbornly demands the master, create a dummy Ppf.esm.

Warning: Only use this if you are absolutely sure no mod needs actual Previs data from the original generated file. For most settlement blueprints, this works fine.
