It is possible to block these numbers if you have activated call forwarding, here is a tutorial that explains how to block these numbers 😀
🤖 Android
Open your Phone app
Go to the Call history
Tap a call from the number you want to block
Tap Block / report spam.
There is also another method, which also allows you to consult the list and remove blocked numbers if necessary:
Open your Phone > Tap More (menu with the three dots) > Tap Settings > Blocked numbers
The list of blocked numbers will appear
You can then add or delete numbers manually
🍏 iOS
In the Recent section of the Phone app
Tap the button Infos (i icon in a circle) next to the number or contact you want to block
Scroll down the screen
then tap Block this Caller
To view the phone numbers you have blocked in Phone: Go to Settings > Phone and touch Blocked contacts to view the list.
For your information, your phone operator can also block numbers at your request
