Steth Question

So I have some Eth staked on lido and received steth in return. After a few people I know told me I can deposit steth to double dip, earn steth rewards and earn rewards on steth coins as well? Does anyone have any suggestions? I’ve checked morpho, and aave but can’t seem to find any information on lending steth in return for more rewards? Ive also heard of curve and harvest but I’m not familiar with either.

Any safe suggestions would be greatly appreciated, as i treasure my Eth and I’m not trying to jeopardize it any way to make a small return. I’m just trying to maximize the amount of Eth I have and letting it work to grow more.

Thanks
