Is it possible to freeze (make immutable) a class or a method in Ruby?

In Ruby:

module Example
  class ExampleValidator
    def mymethod
      # do something important
    end
  end
end

Is it possible to make mymethod immutable (i.e. no monkey patching)?

Otherwise it would also be acceptable to "freeze" the entire class ExampleValidator.

Yes, you can call freeze on a Module.

Example::ExampleVaildator.freeze

However, I'd question why this is necessary. Perhaps it is solving a social problem with a technical one. A tool such as Rubocop should warn about monkey patches.
