Hi there. I've been trying to figure out VAR for a few days now, and finally managed it (another thanks to Wolf too).
I've been able to successfully remove VAR from (I think) every possible competition English teams can play in, including European comps. Goal-line tech remains.
The only exception is the Club World Cup because it was failing the rules test, however I'm not certain it uses VAR anyway.
Hopefully it's useful for you.
The file is for what suits me, I don't manage international teams, so I've not tinkered with World Cup and European Championship stuff etc.
No VAR.fmf
