Your options are either RBF if it's flagged to be replaceable or CPFP the change if it has any.

This doesn't help OP, but Luxor are consistently mining transactions which are replacing non-opted-in transactions, i.e. they are running full RBF. If you can get your replacement transaction to them, then you will be able to use RBF even if your original is not opted in. They are only mining around 1 block a day at present, however.

It's very unlikely that OP's transaction will be removed from the mempool earlier than 14 days.

The mempool usage of my node running default mempool settings is currently around 260 MB. That's very close to the limit of 300 MB at which point low fee transactions start being evicted. It seems other nodes also hit this limit yesterday, and would have started evicting transactions: https://statoshi.info/d/000000020/memory-pool?viewPanel=1&orgId=1&from=now-7d&to=now (note that 286 MiB is equivalent to 300 MB).
