Any progress on root for 920I 5.1.1 knox 0X0?

Hey guys,

I am planning to move to 5.1.1 stock G920IIUS2COH1 for my 920I but I want to know if there is still no possible solution to root without tripping KNOX?
I have 5.0.2 rooted I did not install TWRP to avoid tripping KNOX, is this better to stick like that?

Thank you
