How to disable Nerd Font icons in notifications

[dirn]

I followed the example in the README to disable Nerd Font icons. It seems to cover all of my use cases except for the notifications. I tried setting

format = {
  level = {
    icons = {
      error = "✖",
      warn = "▼",
      info = "●",
    },
  },
},

I even tried opening up config.format and changing the values in there. I still get notifications like this

Here is my config, based on minimal.lua from the wiki.

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "--single-branch",
    "https://github.com/folke/lazy.nvim.git",
    lazypath,
  })
end
print(lazypath)
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  {
    "folke/noice.nvim",
    dependencies = {
      "MunifTanjim/nui.nvim",
      "rcarriga/nvim-notify",
    },
  },
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

-- add anything else here
vim.opt.termguicolors = true
vim.cmd([[colorscheme tokyonight]])
require("noice").setup({
  cmdline = {
    format = {
      cmdline = { icon = ">" },
      search_down = { icon = "🔍⌄" },
      search_up = { icon = "🔍⌃" },
      filter = { icon = "$" },
      lua = { icon = "☾" },
      help = { icon = "?" },
    },
  },
  format = {
    level = {
      icons = {
        error = "✖",
        warn = "▼",
        info = "●",
      },
    },
  },
  popupmenu = {
    kind_icons = false,
  },
  inc_rename = {
    cmdline = {
      format = {
        IncRename = { icon = "⟳" },
      },
    },
  },
})
