Not sure there is a fuse but there is a voltage regulator you could look at.

What leads to your inquiry if there is an 'alternator fuse'?...what symptoms are you seeing, that leads to your question?

Alternator not working. Wanted to make sure if there was a fuse for it or not before putting in the new alternator.

The alternator/Voltage regulator output is commanded by the IBS based upon it sensing battery status. So a bad IBS might not be sending commands, not merely the fact that alternator/VR are 'not working'.
