User Blocking on Huawei 5G CPE Pro 5

I need assistance with my Huawei 5G CPE Pro 5. I want to block unlimited users on this device and am open to any method - MAC address filtering, IP address blocking, or parental controls. The main purpose of this is to restrict access to certain users.

Experience with Huawei network devices is a plus. Please provide details on how you plan to achieve this.
