I finally managed to boot from SPI + NVME (without SD card) but only with original image. I basically followed guide in manual and instead of flashing original I tried to flash Armbian image, but it won't boot at all and hangs on red diod only.
 
Summary of what I did (may help someone):
Create bootable SD card with original OrangePi image downloaded from here Copy image file to SD card you created, ideally to your home folder. Boot it on your OrangePi Install gdisk `sudo apt install gdisk` USe it to delete whole NVME storage `sudo gdisk /dev/nvme0n1` then delete all partitions using `d` command and write changes by `w`. (should no be necessary) Clear nvme storage just to be sure `sudo dd bs=1M if=/dev/zero of=/dev/nvme0n1 count=2000 status=progress` Flash image to NVME storage using command `sudo dd bs=1M if=Orangepi5_x.x.x_debian_bullseye_desktop_xfce_linux5.10.110.img of=/dev/nvme0n1 status=progress` Install bootloader to SPI flash `sudo nand-sata-install` and select option 7 Turn off and remove SD card Turn on and it should boot from SPI + NVME I tried to replace image in step 7. with Armbian image `Armbian_23.02.0-trunk.0112_Orangepi5_jammy_legacy_5.10.110_minimal.img` but it did not booted then.

I have created a Cad drawing of the OPI5 motherboard and a micro desktop case design that can be 3d printed and cnc/laser milled.
https://github.com/berin-aquaquad/orange-pi-5 
The Motherboard cad drawing is or should be 99% accurate. I use Designspark Cad software (free) This is a work in progress, and I have not built it yet. I'm still looking at options I want to add before I build it. As well as any last min. adjustments. The only special aspect I'll point out, is that the main body is designed as a split shell. That is to allow smaller 3d printers to be able to print the main body. I have ordered the GeeekPi Raspberry Pi 4 PWM Fan, Raspberry Pi Low-Profile CPU Cooler with RGB Cooling Fan. When I receive that in the mail, I'll ensure all measurements in my cad file are good and start building. I know there are missing vents and I/O port openings. AGAIN this is a BETA cad file post with a 99% accurate OPI5 SBC board cad file. Anyone who checks it out please give me some feedback. Though I work on luxury yachts I went to school for graphic design.
