SQL Server 2016 is shipped with TLS 1.0 so it will be supported. However, TLS 1.0 itself is now End of Life so its recommended to upgrade it to v1.2 for secure communication.

Frequently asked questions
Is TLS 1.1 supported on SQL Server 2016?
Yes. SQL Server 2016 and SQL Server 2017 on Windows versions ship with TLS 1.0 to TLS 1.2 support. You have to disable TLS 1.0 and 1.1 if you want to use only TLS 1.2 for client-server communication.
