Any way to disable an application rule?

Is there anyway to disable an application rule (not validation) for Cake 3? For instance under buildRules() method I might have a check for sale_price<50, but if I want to remove this rule for current operation is there a call I can make to unset before saving data?

I know I can set checkRules to false when saving, but I don’t want to disable all rules just specified rules.

Did you find any soution to this?

Have you tried these?

The question is not about validation, but application rules. Anyway here is the solution: Conditional application rules

Sorry then I didn’t understand the question.
