As far as I know, once you have entered the pool, there is no way to cancel the transaction. The RBF feature only provides the option to increase or decrease transaction fees as far as I know and does not effectively cancel transactions, if the fee is increased there is a possibility that the transaction will be confirmed more quickly.

We recommend that before sending Bitcoin, we independently check whether the network is congested or not, whether the transaction fee has increased or not to expedite the sending process so that it is fast.

The only way now is to wait for the transaction to be confirmed, it may take 1 or 2 days 😅
