Is there a way to block incoming calls from specific phone numbers?

I want to block a number from calling me. I don't even want to know if the person even tried to call me. Don't want any notifications. The person on the other end should not get a ringing sound when he tries to call me. He shouldn't even know that I've blocked him. **If possible, I would like to block text messages from that number as well.** The specifications of my device can be seen in [the attached image](https://i.sstatic.net/uITcQ.png) : Redmi Note 5, Android 8.1.0, MIUI Global 10.2.3. Is there a way to do it?
