Recommended distros for MPP and RGA support?

I have a Rockpi 4A that’s been working great for years. Just recently I see that Jellyfin has merged Rockchip HWA for video encode/decode and I’d like to use it. I know I need a BSP kernel that supports MPP and RGA. I don’t want to build a kernel myself. So which distro images are people using that includes this kernel support?
