[Q] Remove/Hide soft keys on Android 4.4.x

Hello,

I need to remove the soft keys from my tablet, I tried a lot but I was unable to make it work as it should.
I do not want to use immersive mode cause it hides but the user can get it back on with a swipe...
The only way that I've managed to make something near is to put "qemu.hw.mainkeys=1" on build.prop file, this hides, but once again if I swipe the keys get back visible...

How can I hide it so it does never get back visible no matter what I do?

Thanks
