DPDK has a general aim to convert options from compile-time to run-time.
However, these options would be considered in the last place if ever,
because high VIRT consumption has never been considered harmful before.
If you provide a detailed description of your use case
and explain how and why this interferes with your application needs,
the community can consider this rationale.
Technically, these options are easy to be made dynamic.
