FCC test tools WCN3680B in Qualcomm Platform

I made a custom board using a SOM that has the APQ8053 platform together with WCN3680B. Although the module is FCC precertified, we want to redo the tests of our device because we need our own ID. The EMC part was ok but for all related to WiFi and BT the lab asks us to fix the frequency of the device. I have tried with IW tools but it did not work (wlan0 does not accept my commands). I was googling around and it seems there are Qualcomm tools for it. Does anyone know where should I ask for this tools? I would prefer to do it myself as vendors dont like to disclose tools without selling services. I appreciate if you can point me how to use IW or kernel modifications for it.
