Tailscale add-on configuration (subnet and exit node)

I am linking to this since I haven’t had an answer.
I would like to use Tailscale to connect HA when out of the local network. However, I do not want to use the default settings in HA i.e. Subnet and Exit node.

Echogolf123 wrote the instructions that I was able to follow till the YAML file i.e. “Show unused optional configuration options”. However, I do not know which of those I have to turn off that are not required for the add-on to work.

I also need some help to disable the subnet route access. I am ignorant here, what network should I add “he put as an example 192.168.0.0/24” and how to add the network?. Thank you for helping.
