How to configure hostapd + ath10k CT on DFS channel ?

I tested ath10k and ath10k-ct on my environment with the exact same configurations of hostapd (both options - .11d and .11h are enabled).
In case of the standard ath10k, I could establish a connection between two nodes on a DFS channel (52). The DFS state changed to “available” in "iw list"
On the other hand, I couldn’t connect the nodes with the ath10k-ct. The DFS state was displayed as “usable”.
#Note: to test both drivers I built a LEDE firmware using the following options:
ath10k:
<*> ath10k-firmware-qca988x.............. ath10k firmware for QCA988x devices
<*> kmod-ath10k...................... Atheros 802.11ac wireless cards support
ath10k-ct:
<*> ath10k-firmware-qca988x-ct... ath10k CT 10.1 firmware for QCA988x devices
<*> kmod-ath10k-ct......... ath10k-ct driver optimized for CT ath10k firmware
Thanks,
JL
