Disable catalog discount for attribute price impact

[Jurist]

Hello,

Is it possible to disable catalog discount globally for all attributes and all products? I want price reduction to be applied to base price, while it would have no impact to attribute cost. For example when base price is 100 and attribute impact 10 I want base price to be 80 and attribute 10 after %20 catalog discount. Perhaps prestashop doesnt support such option from back office, so I will probably need to make overrides for some files, anybody have idea where to start?

Thank you
