Slicer works with any OpenVR (SteamVR) compatible headset.
Probably you can hook up your Oculus Go with SteamVR (with adapters such as ALVR), but the experience will be extremely poor/unusable.
I’ve tried Slicer virtual reality with Samsung Gear VR (using vridge) but after some initial enthusiasm I realized that it is so limited compared to a proper VR system (HTC Vive, Windows MR, Oculus Rift) that it just does not make sense. Especially because you can get a Windows Mixed Reality headset with 2 controllers for $300.
