I've still got no clue what an SBC is, but either way the answer is no. For an in-Kodi browser someone needs to pony-up the hours to develop a proper in-Kodi browser, and that's a non-trivial ask. Currently the only (but sucky) option would be running another general purpose distro which has Xorg in the background via chroot or Docker - there's a thread in these forums somewhere on it.
Single Board Computer - SBC, like the Raspberry Pi, Odroid etc.
OK, thank you for the reply, I understand. I found the Docker method thread, but it's not really what I had in mind.
