Sure. If you are using an nvidia optimus laptop, you should also add __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia at the start of the last line when running in hybrid mode to run mpv on the dgpu. You should have a file at ~/.wallpaperrc that contains wallpaper_playlist: /path/to/mpv/playlist. You may want to add this script to your startup sequence via your wm/de.
