Short answer is a NO.

You can also Silence unknown callers. These are all callers that are not in your contact list. This will solve your concern however even legitimate unknown callers will be Silenced. You will not hear the phone ring however a voicemail can be left by the unknown caller. If you want to try it out then, open Settings ➡️ Phone ➡️ SIlence Unknown Callers: Set this to ON.

Finally, you may wish to contact your carrier and see whether they have the means to control the incoming calls in the manner that you want to.
