Is there a way to remove that 5 second delay at boot on the Digispark PRO ?

[Rimbaldo]

 I’ve posted it in an old Digispark (Original) topic, bit as it relates to the PRO, I’ll repost it here. Is there a way, similar to how it was done on the Digispark Original, to remove the 5 seconds delay at the boot of the PRO? In the original an altered bootloader can be written over. Does that bootloader also works on the PRO, or it has a completely different one?

Thanks!
