SpaceX & Jared Isaacman have been awarded an unfunded space act agreement to study boosting the Hubble Space Telescope into a higher orbit, and potentially more. While they haven't gone into great detail about what the plan could be it would be logical to use SpaceX's Dragon spacecraft which has cargo space for payloads which would be required for this kind of mission.
But I think the potential of EVA servicing is still minimal due to the lack of manipulator arms, EVA suits and other hardware that's needed to provide astronaut mobility. However without servicing the telescope could well fail before it falls out of orbit since it's down to one working computer and no spare gyroscopes.
