Solution: You can move the passwords to the parent project whose settings are not committed to a VCS. With clicking to “View DSL”, the Kotlin Code is shown in the Teamcity UI. If the build history is important, it should be restored as soon as possible: after the deletion, there is a configurable timeout (5 days by default) before the builds of the deleted configuration are removed during the build history clean-up.

I do not want the passwords to be committed to the VCS, even in a scrambled form. The portable format does not require specifying the uuid, but if it happened so that a build configuration lost its history, one has to reattach it again via the web interface. TeamCity needs to detect its own commit in the repository, and only after that editing will be enabled. The .teamcity folder contains a maven project consisting of pom.xml file and  the directory with the settings.kts and Project.kt files, as well as buildTypes, pluginData, and vcsRoots subdirectories. baseDir: The directory containing the Kotlin DSL projects and files.
