Disable i586 scheduler

Hello, I am running local OBS instance at Leap 15.6, obs-api-2.10.23. Currently, I have three schedulers: armv7l, i586, x86_64. I would like to completely disable i586. To achieve this I do retrieve the server configuration obs --config ~/.obsadmin_osc.rc api /configuration > obs.config edit <schedulers> section accordingly and upload the configuration back. Then I restart everything. However, I see that i586 scheduler is marked dead at /monitor webui page while I expect that the scheduler will be hidden at that page. What do I do wrong?
