Hi, What are the boot priorities on the Orange Pi Zero 2+ H3 / H5 boards?

SD (MMC0), eMMC (MMC2), SPI NOR, FEL

In case of a working eMMc boot, is it possible to prohibit any boot through SD?

No if you want to still use the SD socket.

* given that secure boot is still not implemented

How is it looks like with the boot priority on the Pi Zero  (with SPI)?

 

So the question is, what about with the Orange Pi Zero when SPI is used and booting from USB... would it prohibit any boot through SD?

Is the priority > SPI flash > SD card > eMMC ?

The same as on other H3/H2+ boards

No. If SD with a bootable image is inserted, the board will boot from SD. Otherwise it will try to boot from eMMC (even if it is not present), after that SPI and fallback to FEL.
