Add CPU support Lenovo M715s

[pashtet440]

Hello folks. Have lenovo m715s with a8 apu. There are ryzen 1 gen in cpu support list, but i think am4 socket and b350 chipset can handle with any other ryzen cpus. Can anyone tell me, is it possible to add 3, 4, 5 gen support to bios? Maybe there are some utilities, instructions to make it?
Thank you for your answers.

Yesterday, I managed to boot the Lenovo M715s with an unmodified BIOS from the Biostar X470GTA motherboard using a Ryzen 5600 CPU. It runs stably—we flashed it using a SOIC clip.

Motherboard in the Lenovo M715s: AM4P2MS Ver 1.1
