First we’ll need to convert that ETH to BNB, transfer the eth to an exchange of your choice.
Exchanges:

KUCOIN is no kyc and you can start using in 3 mins.
But would need KYC to convert to fiat (if you want that lol)
SELL ETH for USDC OR USDT OR UST OR DAI or even better BNB.
NOW that you have BNB setup your metamask to use the bianace start chain:
Mainnet
Network Name: Smart Chain
New RPC URL: https://bsc-dataseed.binance.org/
ChainID: 56
Symbol: BNB
Block Explorer URL: https://bscscan.com
And follow the rest above.
