The QCA6174 radio on the i.MX 8 does not operate in AP mode out of the box.
If you want to enable the radio to operate in AP mode, the easiest way is to use SX-PCEAC2-EVK which includes the QCA6174 based module from Siles.
Silex has also tweaked the NXP BSP to enable soft AP mode so that customers can use this high performance radio as an access point. To learn more on the evaluation kit for the QCA6174 please visit the below link.
