ST-API upgrade component not fitting into target installation

Hello

While upgrading ST-A/PI to 01S_731, I get this message for on of the old third party add ons which we are not using anymore & we are not in any support contract with them.

"component not fitting into target installation"

In the message it says this third party component has a pre-requisite of SAP_ABA 620 but our system is already on SAP_ABA 740.

I m not able to proceed with upgrading ST-A/PI because of this, as I cannot contact the vendor for the Attribute Change Package of the third party component

Is there a way that I can ask SAINT to not check this part or if I can remove the third party add on from the system ?

Thanks
