Buy Defi Pulse Index on Polygon?

Greenhorn here...Apologies if this is has been covered, but I am looking to buy some defi pulse index.

Is it possible to buy/swap it on Polygon/Matic? I don't see it in quickswap, but I do see it listed on https://wallet.matic.network/. If not, is Ethereum the only place I can buy it?

Thanks
