I think your main goal is to ensure that those IDs don’t escape outside of your computer - and open source software is a good start.
There are a mass of serial numbers and other IDs on hardware components - and there isn’t a lot that can necessarily be done
a) not to have those IDs at all, or
b) to change the IDs.
As to specific low level interfaces that might be offered to spoof disk or CPU unique identifiers, I don’t know.
There’s no discrete GPU, so maybe not a concern in this case. Perhaps the display itself has a unique identifier.
A fun way of spoofing some IDs may be to use a VM - so that some or all of the hardware components are virtual anyway.
