How to get zwave razberry2 card to work on raspberry pi 3

This worked before, but I got corrupted SD card. Tried to follow the guide here https://www.home-assistant.io/docs/z-wave/device-specific/#razberry-board

But i have no idea how to run sudo commands like : sudo systemctl disable hciuart
and my last config said:

dtoverlay=pi3-miniuart-bt
enable_uart=1

But that doesn’t seem to help by it self. I am on one of the latest versions.

Please Help. It’s dark here now and soon christmas

You issue those commands from a shell prompt using SSH.

I tried directly on the raspberry as well. How do I get to the correct shell prompt?
and with cli from the gui via Terminal & SSH add on.

Oh you’re using HAOS?

Yes, I am.

Sorry I have no idea with HAOS.

I ditched the pi. Installed it on VMware esxi instead
