You may have emailed me about this...I know, I have a 2019 ;-)
To give you an idea, it's probably possible, I think the Mazda version of this ECM has been "cracked". Likely the only thing stopping the Volvo version from being cracked too, is the expected demand for it, so the vendors that do this routinely, like Alientech for example, they would just need to turn their attention to it, but because Volvo...they haven't. That's my guess anyways.
I can tell you, this is a hardware task. The software update process is protected by signed software and signature check. So the task is taking the hardware ECM, figure out how to read it to get he original program off of it, and figure out how to compromise the signature checking inside the ECM, so it could then be loaded with unsigned calibration.
It requires a very certain set of skills...
