It is possible to block these numbers if you have activated call forwarding, here is a tutorial that explains how to block these numbers 😀
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 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
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
