Yeah, that's basically it, and I guess it's called "Modernist" in Dorico. I'm not in front of my music workstation, and am striking out on finding a link to the documentation right now, but it's available from I think it's called the Notation Options Library. There are a few more Modernist options available having to do with courtesy accidentals. I've yet to get one of these scores in front of an actual group to get feedback, so obviously use your judgement.
