Can I sell my staked ETH on Coinbase?

Could you possibly clarify for me if it's permissible to offload my staked ETH holdings on the Coinbase platform? I've been staking ETH for quite some time now and I'm considering cashing out a portion of it. However, I'm not entirely sure if Coinbase supports the selling of staked ETH or if there are any specific steps or requirements that I need to adhere to. Would you be able to provide some insights into this matter? I'd greatly appreciate any information you could share with me. Thank you in advance for your assistance.
