Larkbox mini Intel(R) Celeron(R) J4115 CPU @ 1.80GHz - Bios and driver update & update to windows 11 need TPM

To be able to update to windows 11 TPM and secure boot is needed.
Therefore I need a bios update compatible with my Larkbox and chipset.
Could you provide me the update with update instruction?

with kind regards
Gerard Koen

It will be hard, as is a discontinued product from long ago.
