How to enbale HTTP/2 on F5 via irule

Not tested but something can be written like this

when CLIENT_ACCEPTED {
set url [string tolower [HTTP::host]]
}

when HTTP_REQUEST {
if { [$url eq "labred.local.ae"] && [HTTP2::active] } {
    pool Lab-red-pool }
elseif { [$url eq "labblue.local.ae"] } {
	 pool Lab-blue-pool }
	}
}
