Scan and advertise on single channel - Bluetooth, Zephyr


I would like to advertise and scan ONLY on one bluetooth channel (for example channel 37). Is there any way to do this in Zephyr? I tried to search parametr responsibles for it in this structure:
struct bt_le_scan_param scan_param = {
.options = BT_LE_SCAN_OPT_NONE,
.interval = 0x0010,
.window = 0x0010,}
but i dont think that this is solution.

I also found a file lll_chan in zephyrproject\zephyr\subsys\bluetooth\controller\ll_sw\nordic\lll. TI includes channel selection algorithms, but i dont see where can i select just one advertising channel?
