How to disable completly the pointer/cursor

[Smartboy]

Before I buy this very nice LG TV with WebOS 23, my wife and I were using an old samsung with an android TV box. So it is very difficult to adapt to the cursor / pointer. I read the documentation and found it is possible to press the direction buttons to momentarely remove the cursor (which is painfull to navigate for us). But each time I press one of the home, return, wheel buttons,  then you know what, the pointer is back on the screen. I read the documentation from A to Z and didn't find any parameter to permanently DISABLE the pointer ... Any workaround or parameter that I missed ?

After some research, I think this is almost impossible to turn off the floating cursor ! Because some applications like the web browser for example is using it. I really think that for elder people, it is very disturbing. In my search I also found some "compatible" remotes where the pointer cannot be activated. BTW, I didn't buy any of these remotes ... This could be a workaround (or not).  I simply reconnected my Android TV box and I am using the very simple Android remote (6 keys ... but not called a magic remote). Another possibility could be to rewrite the webOS it-self from the github web site but I am not sure to want to spend days on that question.
