Hololens: how to render element visible only in AR, but not in mixed reality capture

I'm making a presentation of someone using the Hololens that is duplicated on a big screen. For duplication it uses the device portal's mixed reality capture option (live stream).

I need to render a tool tip to be visible only to the person with the Hololens - but invisible to the people watching it on the big screen.

From what I've seen, the only difference in rendering between the two is that I can render black on the live stream (if I omit rendering the alpha channel) with it being invisible on the Hololens due to the way it's screen works. This is unfortunately useless to me, as I need to show something to the Hololens viewer, not big screen viewers.

Any ideas on how can I make part of the content visible only to the hololens user? I can't use spectator view due to other constraints (I need first person view).

Found a solution, not the best one possible, but usable.

I render the tooltip objects only to the right eye, as only the contents of the left eye are included in the live view.

For anyone wondering, in a shader, there is a magic value of unity_StereoEyeIndex that has the value 1 or 0, depending on the eye. To use this value, it first needs to be set up.

If anoyone has an idea how can I do this without sacrificing stereoscopy, I'll be happy to hear about it.
