I mean “anarchism” is an extremely broad label, to the point of almost being as meaningless as calling oneself a leftist or marxist. A lot of anarchists are pro-direct-democracy, which isn’t consensus based. A specific example is the “inclusive democracy” movement: https://en.wikipedia.org/wiki/Inclusive_Democracy

We have to remember, these labels are all abstractions, they aren’t real concrete relations. They’re just ways that humans divide up and name the world for ease of use.
