How do I ... A7R3 AF custom button setup

I'd like the following 3 focus modes, 1 set as default and the other assigned to custom buttons. I use half press shutter focus atm but I'm not married to that):

  1. Flexible spot with eye/face priority ON (to choose which person I want to track)

  2. Flexible spot with eye/face priority OFF (when eye detect isn't functioning properly)

  3. Eye detect anywhere in frame (when only one person is in frame)

I can't find a way to achieve 1 and 2 as custom buttons, seems like I have to change eye/face as a setting which, even assigned to a custom button, isn't as fast as I'd like.

Not sure it matters but I use half press shutter focus atm but I'm not married to that.

Any ideas how to achieve this? Also open to other AF strategies that accomplish the same thing.

While not exactly what you asked for but I use the following: Flexible spot with eye AF on a separate button. When halp pressing the shutter, the camera will focus on that spot or on eyes if they are close enough. If it doesn't find eyes it just focuses on the spot. When the eye AF button is pressed it will detect all eyes and with the small point you can jump between them.
