if it's mined the only possible way would be to bribe the miners to revert the blocks by paying even more (like time bandit attack) or renting soooo much hashpower to create your own fork. If it's not included yet you need to send another transaction with the same nonce that sends yourself 0 ether but with a higher gas price asap, this is not a guarantee however because the miner would probably still go with the transaction that is more profitable for them and because the fee was so high it got included in under 1 minute. So once this transaction landed in the (public?) mempool it was gg.
