Change docker0 Network

[GitMaster911]

Hi,
i want to run the nginx-manager in a specific subnet 172.20.201.0/24 and i have multiple webservers in 172.17.0.0/16 and 172.18.0.0/16.
But these networks are used of docker0 when i do "ip routes"

I already tried configure netplan but then the server wont start anymore.

Also create /etc/docker/daemon.json and make config wont work.

Do you have other suggestions for me to put the docker network in a APIPA Range which is not used or a specific /24 network ?

Regards
