I guess @vaskebjørn1311 and @The Wizard can give you an exact answer, but if I'm not mistaken the 2. Bundesliga uses the exact same scoreboard as the Bundesliga, but with 2. Bundesliga logos and text instead of the Bundesliga ones. And it seems the DFL-Supercup doesn't use the little league logo on the right side at all. https://totalfootballanalysis.com/a...s-borussia-dortmund-tactical-analysis-tactics
I also haven't watched 2. Bundesliga games for quite some time, but in the last two years the league used the same scoreboard as the Bundesliga but with the 2. Bundesliga logo and text. So I guess it's the same this year too. In regards to the DFL-Supercup I'm not sure if they use a blank scoreboard without the Bundesliga logo and texts or if they at least replace the Bundesliga text with Supercup :/
