Here you select the option "Block number"or"Block contact". The function may have a different name depending on your device and Android version. The contact is then on your blacklist and may have a corresponding icon.

Apps as an alternative

You can also block callers by using an external Android app. In the Play Store you will find numerous apps, including free ones, with which you can block a number. These often have even more diverse functions, for example callers with certain area codes can also be blocked.
