Android 7.1 feature spotlight: A closer look at seamless updates, partition changes, and new fastboot commands
Strange, this is the first time I've seen that's possible. As far as I know they removed the cache partition after they included the seamless updates and changed the system partitions.This article, https://www.bestusefultips.com/wipe-cache-partition-on-android-oreo/, implies that it can be done on Pixel and Pixel XL devices running Android 8.0.
I guess it is incorrect.
