Split light exposures

Looking for the best setting's that most use during a situation such as this:- Shooting a Premier league football match with Nikon D4 and D5 camera's using a 400mm f2.8 lens, On Manual, Auto ISO - The pitch is 50% in bright sunlight and 50% in shadow - Has anyone solved the perfect solution for the best camera setting's for such situations please ?

I am not sure why no one has yet replied. Looking at your Gallery, you seem to be doing what I would have advised. Avoid taking shots of subjects half in and out of the sun but take small groups or individuals in the sun or in the shade. As for camera setting, I would use shutter priority and allow the camera to make the adjustment for exposure for in and out of the shade. There is no single exposure setting which would be perfect for both situations.

Bracketed ISO and then merge in Lightroom or PS. It's no different really to the classic bright sky and dark woods problem in landscapes.
I dont know about the Nikon, but for bracketed ISO my Fuji X-T3 takes one exposure and processes it to create three images, +0, +1 stop, -1 stop. Because it's only one initial exposure, there is no problem of subject movement between the bracketed shots.
If the camera cant do it, expose for the highlights (expose to the right), make a copy and it adjust for the dark areas, then merge.
