Disable Jan 2020 transfer window (in light of new data update)

Is it possible to disable the Jan 2020 transfer window update too?

When starting a new game, you can choose the starting database (20.0) to start your save game with the data as when the game was released in November

Right but using the latest update (i.e. including Winter window). I was these squads to be the same for the 2019/2020 season (i.e. how it actually is). How do I do that?

You want the game not to have a January 2020 transfer window? That's not possible, I'm afraid.

Yeah exactly. I want these newly updated squads to be untouched for the season to increase realism!

your thread title and op is a tad confusing
Perhaps it should be how do I keep real squads for 19/20 season?

if you want to keep all squads as is for whole of 19/20 season either put a transfer embargo in place for all clubs and play out the season

or use a custom start date with/without real fixtures/results and start at the end of may 2020 so the 19/20 season is done with current squads

hope this helps you
I have answered you on another site too

mass edit clubs if you got a high end system it will be fine if not do it in batches based on reputation say 9500-6000 to start

select all in display list and edit as you want
