Hey,

You can do that with
ovn-nbctl lrp-set-gateway-chassis command.

We have documented an example here:

Folks,

I have the following 4 chassis and I would like to change priority so I can decide which one will be active one. I want to make os-chn-gen-comp-002 highest priority. 

How do I change priority? I don't have any L3 routers. All I have are subnets because I am using a vlan tenant provider.
