If you're still around, how would you feel about the concept of a small add in card that acts as an AV1 accelerator either on encode or decode. A small peak power draw of 25-35W but with a staggeringly low power draw. It could have a display adapter, be a small GPU but ultimately it only needs a single PCI-E lane.
Would that convince you to keep your 1070? Or would you consider the power draw of CPU encode/decode (depending on what you have) to be reasonable enough? Does it eventually reach a balancing act, where you'd prefer to have your CPU dedicated to the game instead of encode/decode?
