Is there a way I can block Robocalls?

Yes!  Nomorobo identifies recorded phone calls, spam calls, or other annoyances or scams and actively blocks the calls.

To configure Nomorobo you need to create an account with the Nomorobo service at https://www.nomorobo.com/signup

Nomorobo will take you thru a step by step process to set this up in the SECV user portal.
