According to the technical documents, all pins should be supported for the Orange Pi 4(B). These port mappings are found in the manual and according to the datasheet, all banks should support external interrupts.
However because I don't have an Orange Pi 4, I cannot test these changes. @drizzle1 also can't test these at the moment due to time constraints.
