As of today no wallets provide support to burn fungible tokens.

To burn spammy fungible tokens you can use spl-token command. spl-token command needs the wallet's private keys.

Run solana config get to get your config details.

If Keypair path is set, it'll show up the path to the keypair.json, i,e /Users/userName/folder/keypair.json Otherwise need to set the wallets private keypair by solana config set --keypair keypair_location

Other approach using NodeJS and @solana package

const {Connection, Keypair, PublicKey} = require('@solana/web3.js');
const { burn, getOrCreateAssociatedTokenAccount } = require('@solana/spl-token');
const fs = require('fs');

const RPC_URL = 'https://solana-api.projectserum.com'; 
const KEYPAIR_PATH = "/Users/pathtokeypair/keypair.json";
const secret = JSON.parse(fs.readFileSync(KEYPAIR_PATH));
const fromWallet = Keypair.fromSecretKey(Uint8Array.from(secret));

const payer = fromWallet;

const tokenMint = 'DfP3GKcq86B6VzGQrG3iupRWwqWcWnLndvFC2FTYKxiT'; // a spammy token 

async function burn() {
    const tokenMintPublicKey = new PublicKey(tokenMint);

    const connection = new Connection(
        RPC_URL,
        {commitment:'confirmed', disableRetryOnRateLimit:false, confirmTransactionInitialTimeout:120000},
      );

    const tokenAccount = await getOrCreateAssociatedTokenAccount(
        connection,
        payer,
        tokenMintPublicKey,
        fromWallet.publicKey
    );
  
    const signature = await burn(
        connection,
        payer,
        tokenAccount.address,
        tokenMintPublicKey,
        fromWallet.publicKey,
        amountOfTokens * 9 // tokenDecimals of the tokenMint
        []
    );
    console.log('signature', signature);
    return signature;
}

burn();

Note:- Take caution to not delete valid tokens.
