Yes, you can withdraw your yCRV from yearn anytime after you have deposited it. You can do this by unstaking your st-yCRV and then swapping it for either ETH or USDC. This process is relatively straightforward and can be done through the yearn interface. However, it is important to note that you may incur fees when withdrawing or swapping your yCRV. Therefore, it is important to consider the cost of the transaction when deciding whether to withdraw or swap your yCRV.
