How do i use Ibus reciever in emax mini magnum 2 stack

I have just recieved my emax mini magnum 2 stack for my Hawk 5.
I am using a FS-A8S reciver and a turnigy evolution.
I am not able to use the reciever because the FC only got 1 UART wich is used for sbus and ppm.
Is there a way for me to be able to use ibus in the FC, i have looked around on the internet and read about something called softserial port ( )
And i was wondering if i am able to invert the UART that has sbus and ppm, so that i can use ibus on this wonderfull stack

the SBUS pin should be inverted already.

you may be unable to invert it in the cli
set serialrx_inverted = OFF
set serialrx_halfduplex = ON
