2. Remove prisons from the treasure generation. This can be done in the template editor right now.

3. Ban Alamar, Miriam, and Beatrice.

Heroes can also be banned in the template editor.

And regarding prisons, I'll clarify just in case, since not many people understand the capabilities of the template editor.
Prisons of different levels are separate objects for the generator. They can be banned independently of each other, they can have a limit set on the maximum number in a zone independently of each other. Their average frequency can be changed independently of each other. And all of this can be done both for the entire template and in each individual zone.

That is, the template editor, in this aspect, has a powerful and flexible toolkit, and, in addition to a simple ban, it allows you to set restrictions of various kinds. For example, ban prisons of levels 20 and 30, and set a limit of 1 per zone for prisons of levels 1, 5, and 10. And any other variations of this kind.
