I haven't actually looked into this but it might not be the realm of possibility. But you are generating a frame on GPU, if you can also encode it there, either with nvenc or vulkan doesn't matter. Then DMA the to the nic while just using the CPU to process the packet headers, assuming that cannot also be handled in the GPU/nic

You can also often DMA video coming in through peripherals to get it straight into the GPU, skipping the CPU.
