Presets are just text files you can edit in any text editor. They have slots where you can add your copyright notice and contact info:
crs:Copyright="Copyright 2020 Elmer Fudd"
crs:ContactInfo="Elmer Fudd, 415-555-1212, ..."
Of course, a bad guy could easily edit the file and delete those fields.
You could add some subtle tracking that a bady guy might not notice. Change several of the settings very slightly, e.g. change:
crs:Highlights2012="-50"
to:
crs:Highlights2012="-50.00379"
This will have no effect on the actual image appearance. But it would let you prove that the preset was yours, even if the copyright notice was deleted.
