    Actually, you can't on, as NPN is no longer supported.


    K04412053:  Overview of the BIG-IP HTTP/2 profile


    Activation Modes


    Specifies how the BIG-IP system negotiates HTTP/2 protocol. By default, the BIG-IP system accepts Application Layer Protocol Negotiation (ALPN). 

    Beginning in version 13.1.0, the BIG-IP system no longer supports Next Protocol Negotiation (NPN), which is now deprecated and replaced by the industry standard ALPN published as RFC 7301. Prior to BIG-IP 13.1.0, the NPN is accepted by the BIG-IP system.


    Sorry - you don't really have any options to safely implement HTTP/2.
