[coreboot] Replacing BIOS

[R B]

Dear Sir / Madam,

I bought a mini PC with an N100 CPU and AMI BIOS on Aliexpress. Is it possible to replace the AMI BIOS with coreboot?

Yours sincerely,

Rachid.

P.S. I read on the internet that Chinese equipment may be spying via devices/electronics. Is that true? And will changing BIOS help against this?
