bitcoin core – How do miners generate multiple outputs on a coinbase transaction?

Bitcoin Core hardcodes the Coinbase transaction as a single output. coinbaseTx.vout.resize(1) By definition src/node/miner.cpp

     // Create coinbase transaction.
    CMutableTransaction coinbaseTx;
    coinbaseTx.vin.resize(1);
    coinbaseTx.vin(0).prevout.SetNull();

****************************************************
//Referring to the line of code below 
    coinbaseTx.vout.resize(1);

*****************************************************
    coinbaseTx.vout(0).scriptPubKey = scriptPubKeyIn;
    coinbaseTx.vout(0).nValue = nFees + GetBlockSubsidy(nHeight, chainparams.GetConsensus());
    coinbaseTx.vin(0).scriptSig = CScript() << nHeight << OP_0;
    pblock->vtx(0) = MakeTransactionRef(std::move(coinbaseTx));
    pblocktemplate->vchCoinbaseCommitment = m_chainstate.m_chainman.GenerateCoinbaseCommitment(*pblock, pindexPrev);
    pblocktemplate->vTxFees(0) = -nFees;

    LogPrintf("CreateNewBlock(): block weight: %u txs: %u fees: %ld sigops %d\n", GetBlockWeight(*pblock), nBlockTx, nFees, nBlockSigOpsCost);

However, in the recent block 860062, the mining pool paid several remote miners directly in a coin-based transaction: https://mempool.space/tx/aff7c9b18666c0a51c66013642e24bfcb8b721a674e0f4ce3afa3004b55b0156

How does a miner create a coinbase transaction that overrides the defaults specified in the above Bitcoin Core code snippet?
