If you use Kitty or Wezterm, you don't need patched fonts.

For Kitty, just install the Symbols Nerd Font (it's a fontset that contains only nerd symbols).

For Wezterm, you don't need to do anything, the glyphs are already built in.

JetBrains Mono has been nerdified, in four varieties, for a long time, and is already there. I use it with oh-my-posh.

There are non-ligature and non-monospace (for icons only - everything else is monospace) versions.
