Question Use a normal display to display the left and right eye screen renderings

I want to use Singlepass binocular rendering of the left and right eye images on a normal screen. But I didn't find an effective way. I see that the method is all about XR. You have to turn on the HMD Mock Plugin to achieve a similar effect, but you can't set the parameters for each camera. For example, the projection matrix of the camera, the interpupillary distance of the left and right eyes, etc. Can anyone provide some guidance?
