Yes,  for example for nvidia hardware acceleration we use one of GPU cards
from nvidia to do all the job (encoding/decoding), so we can also use CPU
solutions with an accelerator card (FPGA) for example Alveo U200 from
Xilinx [1] that promises do the same with a lower latency and performance
[2].. so my doubt is if someone tried to go on this path and if it is
economically viable
