vmcall in hypervisor 3.0

There was a example "hook" in Hypervisor 2.0, 
I want to implement sample process in Hypervisor 3.0 .
But I can't find the function " ::intel_x64::vm::call " which was frequently used to implement the "hook" in hypervisor 2.0 .
Is there any function that is similar to " ::intel_x64::vm::call ", or 3.0 can inplement "hook" in other way.
