Chain guard rivets ?

[Scim77]

Looking at the Yamaha Parts catalogue, the chain guard seems to be retained by two screws and two rivets. Are these rivets re-useable or do they need drilling out and replacing?

All plastic and reusable..
The plastic rivets have a pin in the middle that you just push in to release.
