6v6 gameplay pes 2021

Hi, is there a way to modify the number of players on the pitch or the size of the court? I saw a mod for pes2013 that is trying to recreate the kings league and the gameplay is 6v6 I think, is a work in progress but the gameplay is on YouTube. I was wondering if pes 2021 had that potential it would be a big step forward for modding
