Modifying server config file programtically

I have a 'Project' and an 'SFTP' deployment configuration setup.

The 'Deployment path' of the SFTP config needs to change frequently, so in previous editors (Sublime, VS Code) there's a config file that can be modified directly which I used in a git hook to update the server config.

How do I do this with PhpStorm? I mainly need to know where is the deployment configurations file located?

Thanks
