I have accidentally made a transaction with a very low fee (5 sat/byte) and I doubt that it will be confirmed any time soon.
Replace-By-Fee is not available since my transaction has no change.
Abandon the transaction option is also not available.
How can I change the -mempoolexpiry setting in my BitcoinCore (0.20.1), which I run on Windows 10, so that I don't need to wait for 2 weeks for the transaction to be automatically dropped out of the mempool?
