Changing only one parameter in json config

[VladSunny]

Hi!
Can I somehow change and sync only one parameter from complete config?

Example:
I have the Throne app, where the config.json has some dynamic parameters, which I dont want to edit, sync and save.
smthing like this

{
    "active_routing": "Default",
     
     ...
   
    "theme": "QDarkStyle", <--- the only parameter, that I want to save using chezmoi
    
    ... 

    "windows_set_admin": false
}

If there is no feature for this, I will be glad to make a detailed suggestion for a new feature)

Yes, you can do this with a modify_ script or modify template. See https://www.chezmoi.io/user-guide/manage-different-types-of-file/#manage-part-but-not-all-of-a-file.
