With the AX range its recommended to use WPA3, however this is dependant on the devices you are connecting to the WiFi also supporting it.    If you have older devices you may find WPA2 to be a better choice

Enterprise requires a server in place and is likely not what you require for normal home use.

  @Md.Junaid Hi there! In regards to your inquiry about QR codes and security on your Archer AX11000 router, it's great to know that you're taking the necessary steps to ensure the safety of your network. If you set up your network with either WPA2 or enterprise security protocols, your clients should not be able to access your QR code. These security measures provide strong encryption that can help prevent unauthorized access to your network. Let me know if you have any other questions!

  @Md.Junaid i have the same setup as junaid, but my hardware version is V6. for my situation steps are similar...?

Make sure that the QR code is not easily accessible to unauthorized individuals. This could involve placing the QR code in a secure location or only providing it to trusted individuals. Use strong passwords and access controls for your Wi-Fi network. This helps prevent unauthorized access even if someone gets hold of the QR code. Change Wi-Fi passwords and credentials periodically to enhance security. These protocols provide a good level of security. WPA2 Enterprise is particularly useful in business or organizational settings.
