I have used the simple way( prompted by etho201):
1. Using the balenaetcher write the same armbian image to a microSd and to a nvme m.2 SSD too.
2. Put the microSd and the nvme SSD into your orange pi 5.
3. Turn on, load from microSd, start armbian-config, install updates and after that defreeze kernel upgrades.
4. At the same place (armbian-config) write the bootloader on spi MTD, shutdown and remove microSd.
5. Turn on again and load from nvme SSD.
