Can I convert USDT to BNB in MetaMask?

Could you please clarify for me? I'm wondering if it's possible to convert USDT to BNB within the MetaMask platform. I've been exploring the options, but I'm still not quite sure how to proceed. Could you guide me through the process, or perhaps tell me if there are any limitations or considerations I should be aware of? I'm particularly interested in understanding if there are any fees involved and how long the conversion process might take. Your expertise in this area would be greatly appreciated.
