Is it possible to disable a key in MacOs without installing a third party program (e.g. Karabiner)?
One of my keys is stuck and gets pressed continuously.
In Unix it is easy to do with xmodmap, is there an equivalent for mac.

Yes, but not easily
I'm still going to recommend you use Karabiner: it's easy, works well, and does exactly what you need to do. However, if you insist otherwise...
Unless your keyboard happens to be the Caps Lock, Control, Option, Command, or Function key, it cannot be easily remapped or disabled natively. Karabiner is your best bet.
If it is one of those keys, it can be disabled in System Preferences -> Keyboard -> Modifier Keys -> [The key you want] -> No Action.
However, if it's not, you'll have to create a custom keyboard layout. You can either do this by hand(ish), as suggested by Apple, or using a program called Ukelele. There's simplified instructions on apple.stackexchange.com, but I encourage you read the full documentation, it's not the easiest process. However, the main idea is you simply want to unlink the output of the keyboard, then save and install the layout.
