How to update larkbox bios

how update larkbox bios to firmware 5.13?
where i can find the program for it and file with firmware?

any idea?

i want upgrade to win11 but current bios not support any TPM

Just extract the content to your usb. Boot thru usb and install process will begin. This is for the larkbox pro.

Will these bios work with the non pro version of Larkbox?
