Even with that, EU7 won't affect when Porsche decide to end ICE Macan production, as even if EU7 is implemented as proposed in July 2025, it only relates to cars being type approved after that date, not cars being sold.
As we know the Gen III Macan is the last iteration of the ICE Macan design, Porsche could in theory continue to build it for as long as they wanted to (within factory production logistics reasons) without being impacted by EU7, as long as they don't make any changes that require type approval.
Obviously they are not going to build it forever, but they could likely build it to end of MY25 (summer of 2026) without being impacted by EU7. That would allow at least just over a full year of Macan EV production alongside to allow them to see what is happening sales wise.
I doubt they would extend ICE Macan Gen III production alongside EV for longer than that, unless demand was still very high.
