I wrote this function to add gdscript-mode:
-----
(defun eglot-add-gdscript-lsp ()
  (let* ((lsp-port (string-to-number
                    (shell-command-to-string
                     "awk -F'=' '/network\\/language_server\\/remote_port/ {print $2;}' $HOME/.config/godot/editor_settings-4.tres")))
         (lsp-list (cons 'gdscript-mode  (list "localhost" lsp-port
                                               ))))
    (push  lsp-list
           eglot-server-programs)))
