Usually those bolts and nuts hold the large and middle rings, the small ring has 4 bolts visible from the inner side. You might need a special tool to stop the nuts from rotating when loosening or tightening the bolts. Better start with removing the crank arm from the bike to gain access.

My guess is those are permanent rivets disguised a bolts.

absolutely! Don’t forget, these bolts are tightened with a nut. You will need two hex keys to loosen it.
Edit: You will most likely need a chainring nut wrench.

Those rings look like pressed steel which would mean that it is a riveted chainset that can’t be taken apart & the 4 “bolts” are just decorative rivet heads made to look like chainring bolts. I suspect if you look closely you will find the insde of them is round and not shaped to take a hex key.
