How to Disable Proceed Button on selection of Incompatible Product ?

Dear Experts,

We have Eligibility Display Mode =2 . (Post pick Compatibility only Enabled). Rule is based on Compatibility Rule.

As per the vanila, whenever i select in compatible product in econfigurator, Compatibility message will be triggered and we get Proceed and Undo Option. We can click on Proceed button , But In comptible product wont remove(Expected behavior) . If we Click Undo , then It unselect the last selected product due to which compatibility error raised (Expected).

But we want to disable proceed button in this case . How to achieve this ?

If we Enable prepick then those will be hidden (Which we don't want due to certain reasons), but we are looking solution without Prepick.
