Fellow Sony a7iv owner here. I can confirm this works on my camera too.

For older cameras, probably the easiest way to do it (if you don't want to install anything) is to pick up a ~$20 usb HDMI capture card from amazon. Connect the HDMI output on the camera to the capture card. And then set your camera up to output a "clean" video source via the HDMI port.

As I understand it, modern capture cards work without drivers on every OS, just like the modern sony cameras do.
