You are currently on 429 which is Android 10 beta build.
So you cant upgrade it with 087 which is a Android 9 pie stable build.
To get Android 9 pie 087 stable build, you have to manually downgrade to Android 9 first.
Go to asus firmware page, there is a downgrade firmware for Android 10 which will install Android 9 pie 060 build .
After that you will get FOTA updates to latest pie 087 build.
