YES! There is a way. I use my iPad with my Z8 as the first step in my workflow. You will need a HDMI cable and one of these:
4K HDMI Capture

This is a CAPTURE dongle, HDMI to USB-C. If you have a USB-C to HDMI dongle, it will not work. And your iPad MUST have a USB-C port; lightning will not work.
I also recommend a Smallrig HDMI cable, as it’s really thin, short, and easier to deal with than a “regular“ HDMI cable.
EDIT: One more thing, a free app for the HDMI capture is necessary. I tried several and this one had the most minimal interface, which is all that is needed.

Best of luck.
