Disk brakes swap on a new road bike with rim brakes I am planning on buying an Atomic Covert road bike.
Can I put disk brakes on it? Are there adapters for rigid forks/road bikes or do I need to replace parts?
Can I put disk brakes on it?

No. You cannot effectively convert a rim brake frame or forks to disc brakes.
(Alternative answer:

do I need to replace parts?

Yes, the frame and forks.)
Seriously though, if you are buying a new bike, buy the bike you actually want rather than planning to convert or upgrade. There are disc brake road bikes available across a wide range of price points theses days.
