How it's possible to add non-network local connections like xhost command?

I try to run a GUI app in arm64 chroot inside CoreELEC. Is exists some parameter to enable add non-network local connections like xhost command? For example in usual linux distro it’s possible like this:

% xhost +local:root
non-network local connections being added to access control list

CE doesn’t have X. You can’t run GUI applications on it.

Thank you! Maybe it’s possible to use a docker container for this purpose?
