First of all, you must put a configuration file .svlint.toml to specify enabled rules. Configuration file is searched to the upper directory until /. So you can put configuration file (.svlint.toml) on the repository root like .gitignore.

The example of configuration file is below:

exclude_paths = ["ip/.*"]

non_ansi_module = true
wire_reg = true

The complete example can be generated by svlint --example

[option] section

exclude_paths is a list of regular expression. If a file path is matched with the list, the file is skipped to check.

[rules] section

By default, all rules are disabled. If you want to enable some rules, true can be specified.
