I've found this easy tweak to enable double tap to wake on Huawei/Honor devices.
I loved this feature on my old G4, as it was not needed to pick up the phone from a desk, etc. Unfortunately, it seems Huawei does not give a f...k and adds and removes it randomly from its products lineup depending on the weather I guess.
The above instructions are really simple on a ROOTED device. Would any candid soul that already has a rooted mate 10, try to see if the feature is at least available in the system file? (super simple to do with a root explorer). My phone is not rooted, as I'd not like to void the warranty in case I return it since I'm not fully happy so far with this and other Huawei SW neglicencies.
