Power Management blanks screen during gaming

As the topic states I am wondering if there is a way to add an exception to power management if a game or game client (like steam) is running.

Details:
I had been playing on steam/proton since installing Manjaro about a month ago. Steam, unlike RPCS3, did seem to bypass power management. In other words, my 3 minutes screen blank setting was temporarily disabled while gaming, which is good. Then there was an update to steam a few days ago and that functionality seems to have been lost. While I realize this could be a steam or proton issue, the fact that RPCS3 did it prior, leads me to suspect it might be something I could control from within the OS or power management?
