Block unknown incoming calls

[Zayatoshi]

Hello everyone.
I am on Oxygen OS 10.0.6 ROM and I do not see any option to block calls from unknown numbers.
It is possible to block numbers well identified , but no option to block unknown callers.
I know there are third-party applications on the playstore, but with the OP7T's phone application is it possible to block unknown numbers?
Thank you in advance.

Install Google framework module from magisk then you can install Google Phone app and that can block calls from unknown callers. It works because I'm using it atm on my Oneplus 7T
