Any way to boot faster?

I’ve got a X4, and I think the boot process (for BIOS/UEFI) is a bit on the slow side. Fast boot doesn’t help /that/ much. Is there any setting that might speed it up somewhat? It takes about 5 sec even before the Radxa logo shows up. I’m on the latest BIOS.

I compared it with other brands of n100, and it also takes about 5 seconds to get to the BIOS logo.
There are many regions that need to be loaded when starting the BIOS, so I think 5 seconds is reasonable.
It seems that it takes even longer for my PC power to the BIOS.
