Setting IPD on the Oculus - the stereo command was dropped, what should I use now?

I have an old blueprint that allows limited control over a VR camera (currently I’m using the consumer-release Oculus). One part of my blueprint sets the camera’s scale using the stereo e=... engine command. The command has since been removed - I’m not sure when, but there is archived documentation about the command here: Oculus.

I understand how the “World to Meters” scale works (, and my guess is that the stereo command was dropped in favor of using that metric. However, the world to meters scale is referenced by other parts of my application and I don’t wish to change it.

Can anyone help me to find a similar engine command, Blueprint node, or other approach that allows control over just the IPD? I’m using the latest engine release, which is currently 4.20.3.
