Looking for ways to Swap within Wallet ERC20 token for ETH(gas) without sending ETH into Wallet (MetaMask,Trust,,dApp)

Any dApps available to swap ERC-20 token(BAT specifically) for ETH(gas)…. seems like uniswap, or any other dApp etc. requires ETHER(GAS) for transaction… which is main reason I’m trying to do this on the first place…. any dApps, smart contracts, that I’m not aware about someone could point me in the right direction would be great. Seems silly you have to have ETH to send transactions with these wallets..
