Passively managed Bond ETFs hedged in SGD

I was considering iShares JP Morgan USD Asia Credit Bond Index ETF which is listed on the SGX, but later changed my mind because it is not SGD hedged.

I understand that many active managed bond funds will help to hedge the SGD, but the management fee is, for me, too high.

Besides ETFs such as Nikko SGD IG Corp Bond ETF, are there really no other passively managed Bond ETFs denominated in SGD?
