Does the RP have a proper silent mode yet?

The RP only has an electronic first curtain shutter, which negatively impacts bokeh at high shutter speeds. A fully electronic shutter might solve this problem, but as far as I can tell this is only available as a scene mode or using focus stacking. Both options have their own drawbacks, as the silent scene mode doesn't let you manually control exposure and the focus stacking mode requires you to take at least to pictures per shot.

Do any of you know if Canon has added a proper silent mode with manual exposure, or is planning to do so? For me, that would make the difference between purchasing or not purchasing.
