Pentax K mount to RF adapter with manual aperture control lever?

I'm wondering if there's an adapter from Pentax K lenses to the RF mount that also includes a lever and/or dial for controlling the aperture of the lens. I've seen some all-manual ones, like from Fotodiox, but without any aperture control.

But on some adapters I have for other bodies there's a lever or dial that physically moves the shutter (here's an example of one: https://www.amazon.com/Fotasy-Pentax-Adapter-Aperture-Control/dp/B00FAA5NJI). It enables setting aperture on lenses without an aperture ring.

TIA.
