If you want to suppress only a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.
#pragma warning disable IDE0061
// The code that's violating the rule is on this line.
#pragma warning restore IDE0061
To disable the rule for a file, folder, or project, set its severity to none
in the configuration file.
[*.{cs,vb}]
dotnet_diagnostic.IDE0061.severity = none
To disable all of the code-style rules, set the severity for the category Style
