How to disable the prefilling of method signatures with placeholders?

[ayoisaiah]

Or how to jump to each placeholder in SELECT mode?

<Tab> in insert mode.
I set it up to work with luasnip & cmp with this

      ["<Tab>"] = cmp.mapping(function(fallback)
        if cmp.visible() then
          cmp.select_next_item()
        elseif luasnip.expand_or_jumpable() then
          luasnip.expand_or_jump()
        elseif has_words_before() then
          cmp.complete()
        else
          fallback()
          -- end
        end
