Rable I haven't released anything on Steam with it yet so I'm not sure. I'm still early in my current project.
but from discord I saw this quote from 
skymen:
Our game works really well on all platforms including Steamdeck and it builds and uploads at the click of a button
or could ask 
armaldio who made Pipelab.
It does still say it's in Beta though, so maybe he'll talk more about it publicly when it's not beta?
You can also see the Pipelab addon page here, and see what kind of features it supports currently:
