Looking to get Total Control but have a few provinces with >0 autonomy and only 20 years left. I think the answer is no but thought I'd see if anyone has some good ideas.
Most of gov types has it. more advanced types has bigger.Might be too late to help you for this run, but it looks like several government types (I know Iqta is one of them) have a gradual global autonomy decrease. This makes it really easy to get down to 0% without any trouble.
