TS-870 pro upgrade docker ce

I have a TS-870 pro which is locked at QTS 4.3.6.2805, and container station version of 2.0.957. This uses docker version 17.09.1-ce build 0bbe3ac, which is no longer compatible with any of the container registries. I am unable to pull any images. Is there any way to upgrade (the docker version or the Container Station)?

Probably because the kernel version is stuck on that device…Just use that NAS as a NAS and put containers on a different device.
