ath10k: set channel by command "iw" not from hostapd and DFS support of firmware-2.bin_10.1.467.2-1

I am able to run mode access point by using ath10k and hostapd, but I have to set the channel in the configuration file for hostapd (I desactivated ACS when building hostapd)
If I set channel by the command "iw wlan0 set channel 10 HT20"  and remove the line "channel=10" from the configuration file of hostapd, this error appears when I run hostapd: 

ACS was disabled on your build, rebuild hostapd with CONFIG_ACS=y or set channel    
wlan0: IEEE 802.11 Configured channel (0) not found from the channel list of current mode (1) IEEE 802.11g
wlan0: IEEE 802.11 Hardware does not support configured channel
Could not select hw_mode and channel. (-3)
wlan0: Unable to setup interface.
hostapd_free_hapd_data: Interface wlan0 wasn't started

Does it mean that ath10k does not support configured channel ???? The reason I want to do it by command "iw" because it has more options than hostapd (iw wlan0 set freq <control freq> [20|40|80|80+80|160] [<center freq 1>] [<center freq 2>] )

I had another problem with setting a cannal that employs DFS (for example 52): 

wlan0: interface state COUNTRY_UPDATE->DFS                                      
wlan0: DFS-CAC-START freq=5260 chan=52 sec_chan=0                               
wlan0: Unable to setup interface.   
ADDRCONF(NETDEV_UP): wlan0: link is not ready    

I'm using the firmware-2.bin_10.1.467.2-1 which indicates that supports DFS on the website of ath10k. Is there anyone got the same issue like me?
Thanks in advance,
