Is staking USDT/C possible without using an exchange?

My main currency isn’t USD so I keep part of my portfolio as USDT/C as a low risk against my local country inflation on a crypto exchange with a ~5% APR yield.

But now I’m moving from exchanges as my portfolio is getting bigger but I can’t see an option to stake a stablecoin outside. any suggestions or it’s not an option? and I should convert all my USDT assets to SOL and stake them?
