Kali Linux 2019.4 - 2020.1

Hello members please can someone help. I'll be straight forward I don't like the new distros kali linux has implemented in 2020.1 not the separation of live and installation ISOs but the default "non-root user" has created loads of issues for me personally so I cleaned up backed up anything worth saving and reverted back to 2019.4. I ran apt update && apt upgrade -y and from 2019.4 I've had a build upgrade to 2020.1.!!! I though if I didn't run the apt dist upgrade I would get away with it. I want to stay on 2019.4 but be able to update/upgrade the system. How can this be achieved?? Thanks. Kush

P.S I also still have the 2019.3 kali ISO build would that be an option to created usb persistence and update/upgrade from that or will I end up with 2020.1 again??....
