Download the attachment from the first post of this thread bearing in mind that although the attachment is a ZIP file, it is neither a Magisk module nor a restorable ZIP file.
Extract the contents of the ZIP file to get the script named aodenable.sh
Using a suitable root file manager, copy the script to /data/adb/service.d
Set its permissions on rwxr-xr-x (chmod 755)
Restart the device

Alternatively, XDA senior member DanGLES3 has come up with a handy Magisk module that does the same thing mentioned above. For more details, you can take a look at the relevant thread.
