Does the Atom z8300 CPU have additional pins for BIOS SPI memory or another way to start the system?

Question

Do it yourself

Hello. Burned SPI pins for BIOS flash memory on an Intel Atom Z8300 processor. This happened during an attempt to flash the BIOS memory without soldering, and, accordingly, 3.3 Volts came to the processor, instead of the allowable 1.8. It turns out that the system cannot start, because it is impossible to read the BIOS. It became curious, is there an alternative way to start the system? Like connecting BIOSa flash memory to other SPI pins (as far as I remember, this processor has 3 SPI groups) or boot the system via UART (fill BIOS data into RAM? ..). In general, we need an educational program on how the system is loaded from the iron side.

There are no simple options (DCI and JTAG x86 debuggers cost like a cast-iron bridge and you won't get them)
There is an alternative CS# for the second BIOS, but the rest of the lines are common. There are other SPIs, but they are not for the BIOS.
Are you sure the SPI logic pins are burned out? Check with the analyzer, perhaps only the SPI flash drive has died and there are signals on the lines.
Okay BIOS, but on the same flash drive the ME image and the config for the processor and the motherboard, without this, little will start
