How to pass the parameter from trigger to validation rules in Salesforce?

I have a trigger on Contract Object, whenever the contract is updated the Contract section in associated opportunities will also get updated with the latest data but now I am getting validation errors which is created on Opportunity object when we try to update Contract section in Opportunities from Contract trigger.

Now I want to stop Opportunity validation rules whenever an update happen to Opportunity from Contract trigger. Please help how to do this.
