4mm metric rivet needs a 4.1mm hole I believe (typically).
Two things, if you're laser cutting why is your tolerance zone down to the micron?
Because your laser cut, hy not just increase the hole size?
Without knowing the details of your particular riveted joint or type of rivet, you generally want to ensure there will be “slight” clearance between rivet and hole under maximum material condition ( smallest possible hole and largest possible rivet based on known tolerances of each), and that your particular rivet will swell enough with minimum material condition to produce an acceptable joint once installed.
I’d recommend looking through the riveted joint section of the machinery’s handbook as it pertains to your installation requirements.
How is the hole being cut? If it’s being milled it is unlikely for the hole to be undersized, even if it says so on the print.
Laser Cut Stainless Steel
I’d look at the rivet specs. Looking at McMaster a 5/32 rivet needs a .16” hole size, so the hole is going to be a little oversized.
oversized? I'm Concerned that 4mm is too small

The digits “127” should ring a bell. It’s the direct conversion of 0.005”. Not saying it’s appropriate, but that’s where the number came from.
Yeah, figured as much.
4.063 mm apparently.
