Not all firmware branches support raw mode. The firmware will have
raw-mode feature bit enabled if it support raw mode, you can check it
like this:

$ ath10k-fwencoder --info firmware-6.bin_WLAN.RM.4.4.1.c3-00059 | grep Features
Features: wowlan,ignore-otp-result,no-nwifi-decap-4addr-padding,raw-mode,mfp-support

For QCA6174 with raw mode I recommend using 4.4.1.c3 branch:

https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174/hw3.0/4.4.1.c3
