Render in VR without a VR headset

So i’d first like to add my experience with UE is still quite fresh.
We’re trying to have a VR output where the camera will output both the left and right eye as a side by side render.
I’ve got the default VR project in UE5 and with peoples suggestions online, i’ve enabled the steam VR plugin, tried enabling vr.bEnableStereo true, but when i input “vr.bEnableStereo” it just says stereo is disabled. Is there a way to emulate the VR headset or have the side by side eye renders?

Thanks in advance!
