I was looking for a file and came across several scoreboards that I made for previous years... they all work in Fifa 22, which is nice. I am not sure if the Serie A SB is correct or the Brasileiro one... I believe they were at one time. Anyway, if you want to use them, import the .big file to replace either the generic 9002.big overlay file, or -- if you are playing a career with a custom broadcast package (EPL/Bundesliga/etc...) you'll import into the x002.big file of that overlay folder.
Let me know if I can clarify.
This first one is probably only relevant to those of us who watch the EPL here in the US... but it is a pretty cool one because the team color bar is the entire box where the team acronym (3 letters) is. The only tradeoff is when you play a team whose primary color is white, because it makes the letters less legible. To hopefully mitigate this, I made the font color a slightly darker tone and slightly yellowish as well:
