it's been a long time, but way back when we used diamond coated mills. Not coated end mills, like they have now, these looked like a big automotive valve with margarita salt glued all around it. worked great for facing carbon fiber slats and fiberglass.

A fly cutter with a hss bit will last about a minute at best with a pcd insert a bit longer plus the carbon if it is a woven matte it going to fray you would be better off running through a timesaver and probably get a better finish

Use carbide. PCD is better, but not required. We do a lot of fancy vacuum infused carbon composite layup at work, some of our parts need to be machined afterwards. Bringing an HSS endmill to someone setting up a machine to work on a carbon part will get you mocked relentlessly.
Pretty damn quick way to turn an endmill into a nice drill blank, though

You could fly cut it. It'll probably look pretty shitty.
Diamond grit cutters with coolant is how they would do it in industry.

Get coarse grit. Run coolant. It'll work.

You asked about machining it but you didn't say the kind of composite it was. The highest temperature matrix resins out there begin to degrade above 400 F to 425 F region so keeping it really cool is very important.
