What if you played some ultrasound? You can't hear it and the speaker is being used.
AutoIt. Just have it play a Windows ding sound every 4min, but also set the volume to zero first.
Have the script launch at login/startup.
AutoIt doesn't require an install, you can simply copy the script engine to a folder with your script. Been a while, but you may be able to compile your script with the engine too, so you have a stand-alone script.
Or make a silent, 1/4 second long wav/mp3, and use that to ensure you don't hear anything.
because this is a work computer, make sure to name the program something like logitech_driver.exe or something so it and infosec dont get mad
My only issue with this kind of advice is that, if he gets caught using "soundbar_waker.bat", IT might get butthurt but he hasn't really done anything wrong or sketchy. If he's using "Logitech_driver.bat", he's less likely to be caught, but if he is, it's gonna look a lot worse than it really is.
What I’ve done in this scenario is use a very long silent black video from YouTube. There’s a bunch. It technically plays audio, so the soundbar shouldn’t sleep, but the audio is just a silent signal.

The laptop is on Starlink, so the data usage would be noticed. It is a good idea.
