setopt vs. setq-local

[shipmints]

I'm refining my settings per language mode. In some modes, I prefer indent-bars-no-descend-lists to be nil, and in others t. Since you have :set on indent-bars-no-descend-lists, I'm inclined to use setopt but I don't want to reset the global value when I intend setq-local behavior in a mode hook.

What do you recommend as the best way to customize indent-bars settings buffer by buffer?

P.S. The readme says "Note that indent-bars-no-descend-list, which does not require tree-sitter and is on by default" but the code says otherwise (defcustom indent-bars-no-descend-lists nil unless I'm misreading.
