I've got a OnePlus 7T (1905) that I've already installed magisk and TWRP on and disabled the forced encryption. When I try to flash the nethunter image for this phone from the main kali download page I get an error:

*** Dynamic Device Detected ***

This NetHunter package cannot be installed on this device via recovery. Please Flash this file via Magisk Manager as Module And ensure, You have USB DEBUGGING enabled for using ADB

*** NetHunter Installation Failed ***
Am I missing a step? I see the regular OnePlus 7 guide mentions a custom kernel, but I can't find one for the 7T. Is this step still applicable on my device?
