This isn't possible as non-breaking release so is postponed till v4 of this package

Too bad, we are locked to php 8.2 because of this. Any timeline for v4?

No timeline sorry. This package has successfully been tested against PHP8.3: https://github.com/SpartnerNL/Laravel-Excel/actions/runs/8164859885/job/22320971295
