As of right now, no. The only two ways to ride Cosmic Rewind is by either using the virtual queue, or purchasing a Lightning Lane for the attraction. Both Rise of the Resistance at Hollywood Studios, and Remy's Ratatouille Adventure at Epcot have both switched from virtual queue to the classic Standby Line. So based off of that, I would say the Standby Line may eventually be used in the future.
I have a question can you still wait to ride this ride without virtual queue?
