Regional setting affect private league?

Hi, 

I am looking for some advise here. Firstly to summarize our situation: 

Cross platform setup, half the field connects from South Africa and the other half in Europe. What we have realized is the previous seasons when creating the league, I have tried F1 (2022) Africa and in F1 (2023) Europe. We battle with latency issues and "glitching" in race, especially when the racing starts getting closer to each other in battles. Because I am hosting from a PS 5, I cannot host with a VPN active to try and manipulate the connection where both of us are about at 80/90 ms latency. I believe this would be ideal. Now I have thought of two possible ways to fix this but was hoping that someone has gone through this before and could just help me testing things.

1st solution - When creating the league I have an option to chose a different region, maybe Asia would be more central? Or maybe creating it again on Africa?

2nd solution - Buying the game for my PC, creating a non competing user there and run it through a VPN? 

Thanks
