So you have an options page for each post type that basically holds default values for when someone does not add a value to a post I’m guessing. I do something similar. Unfortunately, ACF does not alter the field names based on the options page they are added to. Each field needs a unique key and field name.
You’re going to be modifying the field group and not just the values on a regular basis?
Maybe there is a better solution, can I get more detail on what it is you’re trying to achieve?
