IR pointer wont stay off

[Saintbepis]

Whenever I play metroid other m the game wont exit out of first person view, I'm wondering if theres a way I can make the ir pointer stay on screen or stay off screen at will because the only way I can hide the ir pointer is by pressing L on the classic control (I mapped the hide button  to L in my config file) but i have to keep the button held to make the ir pointer disappear, so what should I modify in my ini file to have the pointer go away permanently or come back at the press of a button.
