Can I configure band preference(2.4Ghz and 5Ghz) for wifi network card using GPO?

Question

I have 2.4Ghz and 5Ghz wifi networks, in the properties of the network card I see that it is possible to use a band preference selection to connect preferentially to networks, for example, 5Ghz. my doubt is whether in my domain environment I could apply similar configuration to all my notebooks

In my research I didn't find this type of property in the GPOS or maybe I could use some modification in the registry.

Is this possible, has anyone done something similar?

There is no native function for that but you can use scripts like this

import time
import pywifi

def connect_to_network(ssid, password):
    wifi = pywifi.PyWiFi()
    iface = wifi.interfaces()[0]
    
    profile = pywifi.Profile()
    profile.ssid = ssid
    profile.auth = pywifi.const.AUTH_ALG_OPEN
    profile.akm.append(pywifi.const.AKM_TYPE_WPA2PSK)
    profile.cipher = pywifi.const.CIPHER_TYPE_CCMP
    profile.key = password
    
    iface.remove_all_network_profiles()
    tmp_profile = iface.add_network_profile(profile)
    iface.connect(tmp_profile)

def main():
    preferred_ssid = "YourPreferredSSID"
    preferred_password = "YourPreferredPassword"

    while True:
        wifi = pywifi.PyWiFi()
        iface = wifi.interfaces()[0]
        networks = iface.scan_results()
        
        for network in networks:
            ssid = network.ssid
            band = "2.4GHz" if network.freq < 5000 else "5GHz"
            
            if ssid == preferred_ssid:
                print(f"Connecting to preferred network: {ssid} ({band})")
                connect_to_network(ssid, preferred_password)
                return
        
        print("Preferred network not found. Retrying in 10 seconds...")
        time.sleep(10)

if __name__ == "__main__":
    main()
