Ltex using local spelling dictionary, or none at all

ltex-ls correctly highlights some words as not spelled correctly. Sometimes, it is wrong and the word is correctly spelled such as a name for example. Neovim spell checker is fine since the weird word is in a spelling file… Ideally, I would like to either:

  1. Remove the ltex spelling altogether.
  2. Have ltex use the local neovim dictionaries.

Can anyone help me there? Apologies, I am not a master of Lua configuration…
