Fast/Instant ETH Transaction via Withdrawal API

Hello,

I didn’t see it anywhere in the API documentation.

Does anyone know if it’s possible to place an withdrawal inserting a fast/instant parameter and/or increasing the max gas fee for ETH network?

Even though such transaction “lanes” are way more expensive, they are also much faster than a normal/standard ETH transaction.

e.g.
Slow - 60 gwei - <30 minutes transaction time
Normal - 67 gwei - <5 minutes transaction time
Fast - 84 gwei - <2 minutes transaction time
Instant - 92 gwei - few seconds transaction time
