Is there a specific workout for 5s sprints?

I strongly disagree.
Running is a totally different beasts. Eccentric muscle contractions vs concentric, different force requirements, etc etc

More mental gymnastics. I asked for a specific TrainerRoad workout to improve my 5s power. I found out that it’s impossible in TrainerRoad software due to not allowing above 300% ftp and now you got people chiming in about outside and what works for them for claiming victory.

There isn’t one, especially not one that works in erg mode. People are explaining why, and giving you alternatives that will help improve your 5s power. You are trying to use the wrong tool for the job, it’s like asking what hammer you need to put a screw in.
