Use magisk to root it. Long as you got adb and fastboot on ur pc and the phone's bootloader is unlocked you can root like this...
1)download the magisk manager.
2)get the ota .zip file for the android version you are running.
3)get payload-dumperwin64.zip and unzip it.
4)unzip the ota.
5)put the payload.bin file from the ota into the input folder for payload dumper.
6)run payload dumper.
7)get the boot.img from the output folder of the payload dumper.
8)copy the boot.img to your phone.
9)open magisk manager.
10)press install, then install, then 'select and patch a file'.
11)select the boot.img
12)once the boot.img is patched it will be renamed magisk_patched.img, copy the magisk_patched.img to your computer.
13)start your phone in fastboot mode
14)on your computer open a command prompt and type 'fastboot flash boot (and the magisk_patched.img file location)'
15)once successful type 'fastboot reboot'
ROoT! Super easy right? And yes, it works with 10 stable. Just make sure to use magisk manager 20.1.
Then as far as twrp goes, you can try flashing the retention module w magisk once ur rooted. IDK if itll work on android 10 or not. I didnt try it.
