Banana BPI-R64 OpenWrt kernel 5.4 image

Hi, recently I purchased BPI-R64 and I would like to run OpenWrt with Home Assistant there.

I downloaded an image but it has an old kernel and it does not allow me to install docker there. I tried to upgrade using LuCI and sysupgrade but broke the kernel.

Is there a recent image for OpenWrt with kernel 5.4 somewhere that I can use to flash to the sd card and install it into the device and start from there?

Or can you advise me on how to get the home assistant running on BPI-R64? Thanks!
