The EPD works.
There is also the fork of xf86-video-fbdev which handles refreshes here:

After spending a while looking getting the NXP kernel to work it seems like it will involve backporting quite a few drivers from 5.7 to 5.4. Not a lot of fun.

So maybe it would be better to go with the newer kernels that you suggested. What bootloader are you using? Is it the existing U-boot from the Kobo or are you building a newer u-boot-imx from NXP's sources?
