camera settings – How to shortcut the “release/focus priority” in the fuji x-t4?

I just bought a fuji x-t4, and since it’s my first fuji camera I’m still lost in the menus. I found the option where I can set if I want it to focus before shooting or shoot right away: It’s called RELEASE/FOCUS PRIORITY and can be found in the AF/MF menu. Here’s a reference:

Now how can I use a shortcut to quickly change it? I’m used to shoot a nikon camera where I’ve set up a shortcut to toggle this option when a “fn” button is pressed.
