I use a custom function eglot-soft-ensure which only enables eglot if
there is already a LSP server running for the current project. This way
eglot doesn’t auto-start in which files that I don’t want it to start.

(defun eglot-soft-ensure ()
  "Turn on eglot when there is an exising server for the current project."
  (require 'eglot)
  (when-let* ((project (project-current))
              (eglot-server (gethash project eglot--servers-by-project)))
    (eglot-ensure)))
