I think you can root through the Magisk app. I did this on the yt9218. I transferred the Boot.img file to the device, modified it via the Magisk app, then transferred the modified Boot.img file back to the PC and uploaded the modified Boot.img via SPFlashtool. After starting, check in Magisk root rights. I also use the Magisk app as a manager for root rights.
edit..
otherwise, if you need it, I flashed TWRP for recovery after rooting. And I only have 1GB of ram, so I removed all google services through TWRP via kill_gapps.zip, then installed the app L_Speed.apk to optimize processes and the system, and the response is significantly faster. I downloaded the app I use outside the play store. I have never used Google Personal account on the main unit for security reasons
