How can I go about creating a bond portfolio that targets about 3.5% with as low volatility as possible? (As opposed to maximizing potential returns with high variability)

I'm willing to sacrifice returns for stability, but how would I go about doing this? Are there any tools to help do this? I'd prefer to stick with index funds, but am open to other options if the fees are somewhat reasonable.
