when generating a database in PowerDesigner I have the option to drop all Tables/Tablespaces and so on before generating the Database: Option to Select

But this Option isnt there when applying changes to a database. I need this, because some local databases could already have some of the Changes I made to the model and I cant drop all tables because of the data.

I'm not sure I understand the question, when you are ready to drop some tables instead of modifying them, but you don't want to drop all tables.

It seems to me that you could use Database > Apply Model Changes to Database with the Connect to a Data Source to compare the model with an existing database, and just generate the necessary modification scripts.

Maybe you could use a saved Selection to generate an Alter Script for most tables, and another to generate a Drop+Create script for some "transient" tables.
