The startOTAUpdate() is the same for all NRF52 boards. Use a common implementation for all boards that currently have a specific implementation. The following boards currently have an empty startOTAUpdate() for whatever reasons and therefore are not inheriting NRF52BoardOTA to keep the same state: Nano G2 Ultra, Seeed SenseCAP T1000-E, Wio WM1110.
