Un-manned F-22 Raptor?

I was wondering if anyone could tell me if there are any plans for an unmanned version of the Raptor to be developed in the near future?
My dad asked me and i haven’t heard anything about an unmanned development and to be honest don’t think that it would be considered yet on such an expensive program developed for a manned craft.
Personally i would think that unmanned fighter aircraft are probably two generations away but that’s a personal thought and maybe well off the mark. If anyone could enlighten me about the F-22 and its possible conversion to unmanned flight would be greatly appreciated. Thanks in advance 😀
