SWAP on unused discrete GPU VRAM

My laptop has limited RAM (only 16 GB) a really crappy nVidia GPU with 4GB of VRAM and because the Intel APU is faster on most benchmarks I never choose to run on the discrete GPU, so the idea is to make some use of the otherwise wasted HW…

I want to replicate this on Fedora: https://wiki.archlinux.org/index.php/Swap_on_video_RAM

Is there a way to set this up or is someone doing it already? Thanks in advance!
